new blog

hey y’all, i decided to combine this blog and personal together and make a new blog where i basically just post whatever the fuck i want without the stress. you can follow the new crib @deftoons ! you’ll of course still be seeing a lot of film-related things and me posting edits from time to time, but it will be a more miscellaneous vibe now! & i recently decided to officially start going by my real name, sav, instead of maxine now, will be tracking a new tag #userdef - you’re welcome to tag me in anything film or music related!

Django Models (1054, "Unknown column in 'field list'")

No idea why this error is popping up. Here are the models I created -

from django.db import modelsfrom django.contrib.auth.models import Userclass Shows(models.Model): showid= models.CharField(max_length=10, unique=True, db_index=True) name = models.CharField(max_length=256, db_index=True) aka = models.CharField(max_length=256, db_index=True) score = models.FloatField()class UserShow(models.Model): user = models.ForeignKey(User) show = models.ForeignKey(Shows)

Here is the view from which I access these models -

from django.http import HttpResponsefrom django.template import Contextfrom django.template.loader import get_templatefrom django.http import HttpResponse, Http404from django.contrib.auth.models import Userdef user_page(request, username): try: user = User.objects.get(username=username) except: raise Http404('Requested user not found.') shows = user.usershow_set.all() template = get_template('user_page.html') variables = Context({ 'username': username, 'shows' : shows}) output = template.render(variables) return HttpResponse(output)

At this point I get an error -

OperationalError: (1054, "Unknown column 'appname_usershow.show_id' in 'field list'")

As you see this column is not even present in my models? Why this error?

Creating a extended user profile

I have an extended UserProfile model in django:

class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) #other things in that profile

And a signals.py:

from registration.signals import user_registeredfrom models import UserProfilefrom django.contrib.auth.models import Userdef createUserProfile(sender, instance, **kwargs): profile = users.models.UserProfile() profile.setUser(sender) profile.save()user_registered.connect(createUserProfile, sender=User)

I make sure the signal gets registered by having this in my __init__.py:

import signals

So that should create me a new UserProfile for every user that registers, right? But it doesn't. I always get "UserProfile matching query does not exist" errors when I try to log in, which means that the database entry isn't there.

I should say that I use django-registration, which provides the user_registered signal.

The structure of the important apps for this is, that I have one application called "users", there I have: models.py, signals.py, urls.py and views.py (and some other things which shouldn't matter here). The UserProfile class is defined in models.py.

Update: I changed the signals.py to:

from django.db.models.signals import post_savefrom models import UserProfilefrom django.contrib.auth.models import Userdef create_profile(sender, **kw): user = kw["instance"] if kw["created"]: profile = UserProfile() profile.user = user profile.save()post_save.connect(create_profile, sender=User)

But now I get a "IntegrityError":

"column user_id is not unique"

Edit 2:

I found it. Looks like somehow I registred the signal twice. The workaround for this is described here: http://code.djangoproject.com/wiki/Signals#Helppost_saveseemstobeemittedtwiceforeachsave

I had to add a dispatch_uid, now my signals.py looks like this and is working:

from django.db.models.signals import post_savefrom django.contrib.auth.models import Userfrom models import UserProfilefrom django.db import modelsdef create_profile(sender, **kw): user = kw["instance"] if kw["created"]: profile = UserProfile(user=user) profile.save()post_save.connect(create_profile, sender=User, dispatch_uid="users-profilecreation-signal")

Wrong dashboard while adding flask-admin to project

I'm trying to extend the flask-base project https://github.com/hack4impact/flask-base/tree/master/app. This uses the the application factory pattern in app/init.py and blueprints.

In the app/init.py I have:

import osfrom flask import Flaskfrom flask_mail import Mailfrom flask_sqlalchemy import SQLAlchemyfrom flask_login import LoginManagerfrom flask_assets import Environmentfrom flask_wtf import CsrfProtectfrom flask_compress import Compressfrom flask_rq import RQfrom flask_admin import Admin, BaseView, exposefrom flask_admin.contrib.sqla import ModelView# from app.models import Userfrom config import configfrom .assets import app_css, app_js, vendor_css, vendor_jsbasedir = os.path.abspath(os.path.dirname(__file__))mail = Mail()db = SQLAlchemy()csrf = CsrfProtect()compress = Compress()# Set up Flask-Loginlogin_manager = LoginManager()login_manager.session_protection = 'strong'login_manager.login_view = 'account.login'from app.models import Userdef create_app(config_name): app = Flask(__name__) app.config.from_object(config[config_name]) app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False # not using sqlalchemy event system, hence disabling it with app.app_context(): m =app.url_map config[config_name].init_app(app) # Set up extensions mail.init_app(app) db.init_app(app) login_manager.init_app(app) csrf.init_app(app) compress.init_app(app) RQ(app) # adm = Admin(app, name='MyAPP') adm = Admin(endpoint='adminz', name='adz', url='/adminz') ...... # Create app blueprints from .main import main as main_blueprint app.register_blueprint(main_blueprint) from .account import account as account_blueprint app.register_blueprint(account_blueprint, url_prefix='/account') from .admin import admin as admin_blueprint # from .admin import admin_blueprint app.register_blueprint(admin_blueprint, url_prefix='/admin') return app

templates/admin/db.html:

<p>Hello world</p>

To the admin views (https://github.com/hack4impact/flask-base/blob/master/app/admin/views.py) I've added :

from flask_admin import Admin, BaseView, exposefrom flask_admin.contrib.sqla import ModelViewfrom app import adm as adm, dbclass MyView(ModelView): @expose('/') def db(self): return self.render('admin/db.html')# admin management setup@main.route('/db')def db(): adm.add_view(MyView(User, db.session))

I'm getting the admin dashboard not the flask-admin basic view when I open:

127.0.0.1:5000/db

What am I doing wrong?

EDIT:

following your directions I changed create_app to start with:

def create_app(config_name): app = Flask(__name__) app.config.from_object(config[config_name]) app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False # not using sqlalchemy event system, hence disabling it # adm = Admin(name='admin2', endpoint='/db', url='/db', template_mode='bootstrap3',base_template='admin/db.html') config[config_name].init_app(app) # Set up extensions mail.init_app(app) db.init_app(app) login_manager.init_app(app) csrf.init_app(app) compress.init_app(app) RQ(app) adm = Admin(app, name='MyAPP') # adm = Admin(endpoint='adminz', name='adz', url='/adminz') adm.add_view(MyView(User, db.session, endpoint='db'))

This results in :

File "....flask\app.py", line 946, in register_blueprint (blueprint, self.blueprints[blueprint.name], blueprint.name)AssertionError: A blueprint's name collision occurred between and . Both share the same name "admin". Blueprints that are created on the fly need unique names.

EDIT2:

to the end of create_app I've added:

# Create app blueprintsfrom .main import main as main_blueprintapp.register_blueprint(main_blueprint)from .account import account as account_blueprintapp.register_blueprint(account_blueprint, url_prefix='/account')from .admin import admin as admin_blueprint# from .admin import admin_blueprintapp.register_blueprint(admin_blueprint, url_prefix='/admin')# app.register_blueprint(admin_blueprint, url_prefix='/ab')with app.app_context(): m =app.url_mapreturn app

I'm not sure what you want to see but m.rules gives:

<Rule '/account/manage/change-password' (HEAD, GET, OPTIONS, POST) -> account.change_password>, <Rule '/account/manage/change-email' (HEAD, GET, OPTIONS, POST) -> account.change_email_request>, <Rule '/account/manage/info' (HEAD, GET, OPTIONS, POST) -> account.manage>, <Rule '/account/confirm-account' (HEAD, GET, OPTIONS) -> account.confirm_request>, <Rule '/account/reset-password' (HEAD, GET, OPTIONS, POST) -> account.reset_password_request>, <Rule '/account/unconfirmed' (HEAD, GET, OPTIONS) -> account.unconfirmed>, <Rule '/account/register' (HEAD, GET, OPTIONS, POST) -> account.register>, <Rule '/account/logout' (HEAD, GET, OPTIONS) -> account.logout>, <Rule '/account/manage' (HEAD, GET, OPTIONS, POST) -> account.manage>, <Rule '/account/login' (HEAD, GET, OPTIONS, POST) -> account.login>, <Rule '/admin/_update_editor_contents' (OPTIONS, POST) -> admin.update_editor_contents>, <Rule '/admin/invite-user' (HEAD, GET, OPTIONS, POST) -> admin.invite_user>, <Rule '/admin/new-user' (HEAD, GET, OPTIONS, POST) -> admin.new_user>, <Rule '/admin/users' (HEAD, GET, OPTIONS) -> admin.registered_users>, <Rule '/get_session_job_value' (HEAD, GET, OPTIONS) -> main.get_session_job_value>, <Rule '/cl_confirm_chrome' (HEAD, GET, OPTIONS, POST) -> main.cl_confirm_chrome>, <Rule '/render_png' (HEAD, GET, OPTIONS) -> main.render_png>, <Rule '/selected' (HEAD, GET, OPTIONS) -> main.selected>, <Rule '/cl_dash' (HEAD, GET, OPTIONS, POST) -> main.cl_dash>, <Rule '/about' (HEAD, GET, OPTIONS) -> main.about>, <Rule '/admin/' (HEAD, GET, OPTIONS) -> admin.index>, <Rule '/dash' (HEAD, GET, OPTIONS) -> main.dash>, <Rule '/jobs' (HEAD, GET, OPTIONS) -> main.get_jobs>, <Rule '/' (HEAD, GET, OPTIONS) -> main.index>, <Rule '/account/manage/change-email/<token>' (HEAD, GET, OPTIONS, POST) -> account.change_email>, <Rule '/admin/user/<user_id>/change-account-type' (HEAD, GET, OPTIONS, POST) -> admin.change_account_type>, <Rule '/admin/user/<user_id>/change-email' (HEAD, GET, OPTIONS, POST) -> admin.change_user_email>, <Rule '/admin/user/<user_id>/_delete' (HEAD, GET, OPTIONS) -> admin.delete_user>, <Rule '/admin/user/<user_id>/delete' (HEAD, GET, OPTIONS) -> admin.delete_user_request>, <Rule '/admin/user/<user_id>/info' (HEAD, GET, OPTIONS) -> admin.user_info>, <Rule '/account/join-from-invite/<user_id>/<token>' (HEAD, GET, OPTIONS, POST) -> account.join_from_invite>, <Rule '/account/confirm-account/<token>' (HEAD, GET, OPTIONS) -> account.confirm>, <Rule '/account/reset-password/<token>' (HEAD, GET, OPTIONS, POST) -> account.reset_password>, <Rule '/admin/static/<filename>' (HEAD, GET, OPTIONS) -> admin.static>, <Rule '/admin/user/<user_id>' (HEAD, GET, OPTIONS) -> admin.user_info>, <Rule '/results/<job_key>' (HEAD, GET, OPTIONS) -> main.get_results>, <Rule '/static/<filename>' (HEAD, GET, OPTIONS) -> static>

EDIT 3:

I have to say that is an incredible answer! You have really taught me a lot. I have replaced the urls with the rules above following your directions. My original plan 10 days ago was just to use the basic flask-admin CRUD functionality. I'm not interested in the db.html template (its just something I tried).

anyway trying to change the name of the admin blueprint ( your number 1). I had tried this before changing app/admin/init.py to :

from flask import Blueprintadmin = Blueprint('admin_blueprint', __name__)from . import views # noqa

Now when I open

http://127.0.0.1:5000/adminz/

I get a 404 error

FINAL EDIT:

The problem was solved by https://chat.stackoverflow.com/users/5819113/diego-quintana who explained that there was a conflict between flask-admin which creates a blueprint and the flask-base admin blueprint. By changing both the name of the blueprint and the static file folder of the flask-base project. Flask-admin could work without being overridden. Please see https://github.com/kc1/flask-base

Isolating py.test DB sessions in Flask-SQLAlchemy

I'm trying to build a Flask app with Flask-SQLAlchemy; I use pytest to test the DB. One of the problems seems to be creating isolated DB sessions between different tests.

I cooked up a minimal, complete example to highlight the problem, note that test_user_schema1() and test_user_schema2() are the same.

Filename: test_db.py

from models import Userdef test_user_schema1(session): person_name = 'Fran Clan' uu = User(name=person_name) session.add(uu) session.commit() assert uu.id==1 assert uu.name==person_namedef test_user_schema2(session): person_name = 'Stan Clan' uu = User(name=person_name) session.add(uu) session.commit() assert uu.id==1 assert uu.name==person_name

If the db is truly isolated between my tests, both tests should pass. However, the last test always fails, because I haven't found a way to make db sessions rollback correctly.

conftest.py uses the following based on what I saw in Alex Michael's blog post, but this fixture code breaks because it apparently doesn't isolate the db sessions between fixtures.

@pytest.yield_fixture(scope='function')def session(app, db): connection = db.engine.connect() transaction = connection.begin() #options = dict(bind=connection, binds={}) options = dict(bind=connection) session = db.create_scoped_session(options=options) yield session # Finalize test here transaction.rollback() connection.close() session.remove()

For the purposes of this question, I built a gist, which contains all you need to reproduce it; you can clone it with git clone https://gist.github.com/34fa8d274fc4be240933.git.

I am using the following packages...

Flask==0.10.1Flask-Bootstrap==3.3.0.1Flask-Migrate==1.3.0Flask-Moment==0.4.0Flask-RESTful==0.3.1Flask-Script==2.0.5Flask-SQLAlchemy==2.0Flask-WTF==0.11itsdangerous==0.24pytest==2.6.4Werkzeug==0.10.1

Two questions:

Why is status quo broken? This same py.test fixture seemed to work for someone else.

How can I fix this to work correctly?

Querying model in Flask-APScheduler job raises app context RuntimeError

I want to run a job with Flask-APScheduler that queries a Flask-SQLAlchemy model. When the job runs, I get RuntimeError: application not registered on db instance and no application bound to current context. How can I run a job that queries the database.

from flask_apscheduler import APSchedulerscheduler = APScheduler()scheduler.init_app(app)scheduler.start()

from models import Userdef my_job(): user = User.query.first() print(user)

The error occurs during the query, before it can be printed. The database is working in the rest of the application for other queries.

I tried to add with app.app_context(): while setting up the extension but that didn't work.

with app.app_context() scheduler = APScheduler() scheduler.init_app(app) scheduler.start()

The full traceback is:

Django: Model Form "object has no attribute 'cleaned_data'"

I am trying to make a search form for one of my classes. The model of the form is:

from django import formsfrom django.forms import CharField, ModelMultipleChoiceField, ModelChoiceFieldfrom books.models import Book, Author, Categoryclass SearchForm(forms.ModelForm): authors = ModelMultipleChoiceField(queryset=Author.objects.all(),required=False) category = ModelChoiceField (queryset=Category.objects.all(),required=False) class Meta: model = Book fields = ["title"]

And the view I'm using is:

from django.shortcuts import render_to_response, redirect, get_object_or_404from django.template import RequestContextfrom books.models import Book,Authorfrom books.forms import BookForm, SearchFormfrom users.models import Userdef search_book(request): if request.method == "POST": form = SearchForm(request.POST) if form.is_valid(): form = SearchForm(request.POST) stitle = form.cleaned_data['title'] sauthor = form.cleaned_data['author'] scategory = form.cleaned_data['category'] else: form = SearchForm() return render_to_response("books/create.html", { "form": form, }, context_instance=RequestContext(request))

The form shows up fine, but when I submit it I get an error: 'SearchForm' object has no attribute 'cleaned_data'

I'm not sure what's going on, can someone help me out? Thanks!
