Django 2.0: sqlite IntegrityError: FOREIGN KEY constraint failed
I'm working on adding Django 2.0 support to the django-pagetree library. During automated testing, using an sqlite in-memory database, I'm getting a bunch of errors like this: File "/home/nnyby/src/django-pagetree/pagetree/tests/test_models.py", line 638, in setUp 'children': [], File "/home/nnyby/src/django-pagetree/pagetree/models.py", line 586, in add_child_section_from_dict ... File "/home/nnyby/src/django-pagetree/venv/lib/python3.5/site-packages/django/db/backends/base/base.py", line 239, in _commit return self.connection.commit() django.db.utils.IntegrityError: FOREIGN KEY constraint failed This is noted in the Django 2.0 release notes: https://docs.djangoproject.com/en/2.0/releases/2.0/#foreign-key-constraints-are-now-enabled-on-sqlite From that description, which I don't fully understand, this shouldn't apply for test databases that aren't persistent, right? Wouldn't my sqlite test db get created with the appropriate options when using Django 2.0? The app settings I'm using for testing are here: https://github.com/ccnmtl/django-pagetree/blob/master/runtests.py -
using a if statement in a generic detail view
I am having trouble to figure out how to manage my error: my app is built that way : a user create a project the user is redirected to a project detail page The user is asked to create a team and add members to that project The user is again redirected to the project detail page rendering now the team name and a list of all the team members. My problem is that I wanted to add a context_data to render in my HTML def get_context_data(self, **kwargs): context = super(ProjectDetailView, self).get_context_data(**kwargs) team_name = Project.objects.get(id=self.kwargs['pk']).team_id.members.all() context['team_name'] = team_name return context but now when I create a project since there is no team and member yet, I am getting an error 'NoneType' object has no attribute 'members' How can I do? is there a way to add a if statement in a view ? -
Django sometimes gives 404 and sometimes gives 200

Django Model Inheritance - get child
Is there a way to access the actual child of the base model, means: Staying with the example from the django Docs, let's assume I am modeling different delivery restaurants, that just have in common name all have a deliver method as of this: class Place(models.Model): name = models.CharField(max_length=10) class Pizzeria(Place): topping = models.CharField(max_length=10) tip = models.IntegerField() def deliver(self): deliver_with_topping(self.topping) ask_for_tip(self.tip) class Shoarma(Place): sauce = models.CharField(max_length=10) meat = models.CharField(max_lenght=10) def deliver(self): prepare_sauce_with_meat(self.sauce, self.meat) I would now like to execute: Place.objects.get(name="my_place").<GENERIC_CHILD>.deliver() i.e. I don't need to know what the place is actually, just the common deliver method. The model then 'knows' what to call. Is there something like <GENERIC_CHILD>? -
unable to download csv from django admin on HEROKU

Django-channels - recieve data based on url
I'm very new to django-channels so this is probably a very simple question. On our website, there is a permanent button "Messages" in the header. I want user to be notified about new message immediately. So I use channels for this purpose. If there is a new message created, I send a number of not readed conversations through channels to client: class Message(..): def save(...): notify_recipient(self) def notify_recipient(self): Group('%s' % self.recipient).send({ "text": json.dumps({ "message":{"text":truncatechars(self.text,100)}, "unreaded_conversations":Conversation.objects.get_unreaded_conversations(self.recipient).count(), }), }) And in base.html: const webSocketBridge = new channels.WebSocketBridge(); webSocketBridge.connect('/notifications/'); webSocketBridge.listen(function (action, stream) { console.log(action, stream); var conversations_sidebar = $('#id_conversations_sidebar'); var messages_list = $('#messagesList'); if (action.unreaded_conversations) { $('#id_unreaded_conversations_count').text(action.unreaded_conversations); } On the other hand, there is a page /chat/detail/<username>/ where users chat with each other. This chat should be live so I need to recieve messages through channels. For now, I've added rendered message to the notify_recipient method but the problem is that it has to render the message allways, even when user is not on this /chat/detail/<username>/ url which is not efficient. Do you know how to recieve rendered messages only when user is in the current chat? routing.py @channel_session_user def message_handler(message): message.reply_channel.send({"accept": True}) @channel_session_user_from_http def ws_connect(message,): Group("%s" % message.user).add(message.reply_channel) message.reply_channel.send({"accept": True}) channel_routing = … -

How to validate on read only field in Django Rest Framework
I'm trying to add a vote functionality to the code found in tutorial of Django Rest Framework. On top of Snippet model, I added a Vote model: class Vote(models.Model): created = models.DateTimeField(auto_now_add=True) voter = models.ForeignKey(User, on_delete=models.CASCADE) snippet = models.ForeignKey(Snippet, related_name='votes', on_delete=models.CASCADE) class Meta: ordering = ('created',) In my serializer, I'm trying to validate the fact that user cannot vote more than once and cannot vote for his own snippet: class VoteSerializer(serializers.HyperlinkedModelSerializer): voter = serializers.ReadOnlyField(source='voter.username',validators=[UniqueValidator(queryset=Vote.objects.all(), message=already_voted)]) snippet = serializers.PrimaryKeyRelatedField(queryset=Snippet.objects.all()) def validate(self, data): snippet = data.get('snippet') voter = data.get('voter') if voter==data['snippet'].owner: raise serializers.ValidationError(u"Voter cannot vote for himself.") return data Voter field must be read-only.

Best practice setup for two websites with different style sheets and templates, but similar Django back end
I'm working on a Django back end that will be used by two websites (i.e., a job board for non-profits and a job board for for-profit companies), but I'm not sure how this is best structured to make it easy to push/pull updates to the two websites. The Django code for the websites is highly similar (let's say over 95% overlap), but the websites have slightly different templates and separate CSS style sheets, in order to give each a distinct look and feel. My inclination would be to set this up as a single Django project that stores the CSS style sheets for both websites, has a different templates folder for each website, and has multiple settings files (e.g., base, production_fprofit, production_nprofit). To facilitate any current or future differences in the back end, a settings variable would indicate the platform for which the code is used (e.g., FPROFIT = True/FPROFIT = False) and this variable is called when necessary (e.g., if settings.FPROFIT == True: self.context_dict["profile_form"] = TRUE). Whenever the Django code changes, the code is pushed to GIT and pulled by the two platforms - each running on a separate virtual host, with their own testing, staging, and production environments. … -

Django : how to extract items of another table from one table if they are related by foreign key

HTTP 404, Not Found. Django
I am developing an e-learning website on django 1.11. When going through the website, I am getting HTTP 404, Not Found in the terminal (as shown in the image). This is not the usual 404 error caused by misspelling of the url, because on the browser side the page renders properly (but sometimes keeps on waiting and waiting) and I am not sure what is causing the error. The error looks like this: Error in Powershell In this image, we can see that HTTP returns 200, when asked for subject list page. When the subject select page is requested it first returns 200 (success) but then it returns two 404 errors (I am not sure where they are coming from.) This error has not stopped the server but I do not know whether this error is harmful for production or not. What kind of error is this? How can I get rid of this?

I have no idea why.. serverlist.html- <div class="container"> <br> <center><h1 class="display-4">DevOps Server List</h1></center> <br> <center><button type="button" class="save btn btn-outline-success btn-lg" data-toggle="modal" data-target=".AddServer">Add Server <i class="fa fa-server fa-lg" aria-hidden="true"></i></button></center> <table class="table table-hover table-bordered table-condensed" cellspacing="0" width="1300" id="ServerTable"> <thead> <tr> <th><center> #</center></th> <th><center> Server Name </center></th></center> <th><center> Owner </center></th></center> <th><center> Project </center></th></center> <th><center> Description </center></th></center> <th><center> IP Address </center></th></center> <th><center> ILO </center></th></center> <th><center> Rack </center></th></center> <th><center> Status </center></th></center> <th><center> &nbsp;&nbsp;&nbsp;&nbsp; Actions &nbsp;&nbsp;&nbsp;&nbsp; </center></th></center> </tr> </thead> <tbody> {% for server in posts %} <tr> <div class ="server"> <td></td> <td><center>{{ server.ServerName }}</center></td> <td><center>{{ server.Owner }}</center></td> <td><center>{{ server.Project }}</center></td> <td><center>{{ server.Description }}</center></td> <td><center>{{ server.IP }}</center></td> <td><center>{{ server.ILO }}</center></td> <td><center>{{ server.Rack }}</center></td> <td><h4><span class="badge badge-success">Online</span></h4></td></center> <td> &nbsp;&nbsp;&nbsp;&nbsp; <button type="button" class="btn btn-outline-danger" data-toggle="modal" href="#delete-server-{{server.id}}" data-target="#Del{{server.id}}">Delete <i class="fa fa-trash-o"></i></button>&nbsp; <button type="button" class="btn btn-outline-primary" data-toggle="modal" href="#edit-server-{{server.id}}" data-target="#Edit{{server.id}}"> &nbsp;&nbsp;Edit&nbsp; <i class="fa fa-pencil"></i></button> &nbsp; <div id ="Del{{server.id}}" class="modal fade" role="document"> <div class="modal-dialog" … -
Import external react component from CDN (React Bootstrap Slider)
I have a Django project and I want to use React on it. I have already created my own components and this works, but I dont know how to import third-party components from CDN. To do this, I did: Import React (develop or production version) in the base template: <!-- baseTemplate.html --> {# ReactJs#} <script src="https://unpkg.com/react@16/umd/react.development.js"></script> <script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script> <script src="https://unpkg.com/babel-standalone@6.15.0/babel.min.js"></script> Also import the file where I create my components <!-- baseTemplate.html --> <script src="/one_directory/my_react.jsx" type="text/babel"></script> and create the tag where it will be rendered. <!-- template.html --> <div id="container"></div> And finally render my React components: <!-- my_react.jsx --> ReactDOM.render( <App />, document.getElementById('container') ); This works correctly :) Now, I want to import a third-party component (specifically, it's React Bootstrap Slider) from CDN, but I dont know how. Maybe this is not possible, I dont know. How could I do it? Thank you very much :] -
the miss "meida" path in django-oscar image URL
I m trying django-oscar to build an e-commerce website. I have deployed django-oscar on Heroku (with Amazon S3 as static and media file bucket), the issue is When I try to add a photo for a product on dashboard, The system returns the correct working URL https://s3.amazonaws.com/mybucket/media/cache/XXX/YYY/ZZZ.jpg that works on first page view request. Reload the page. The system returns broken URL: https://s3.amazonaws.com/mybucket/cache/XXX/YYY/ZZZ.jpg (missing 'media' path) any idea about this miss "media"? -
python - mock, patch, start and return_value
When using mock patcher with start() (and stop() later on) - does it matter when I add the return_value? For example - is there a difference between - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_patcher.return_value = 'some_deleted_attachment_urn' cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() and - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() cls._dm_delete_attachment_start.return_value = 'some_deleted_attachment_urn' or maybe it should be - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_patcher.return_value = 'some_deleted_attachment_urn' cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() cls._dm_delete_attachment_start.return_value = 'some_deleted_attachment_urn' In my test, seems like the first option failed, and the third did the work. I'm not sure why.
