Django rest framework integrate 2 different django project API

Django: Server Error (500) when Debug is False
I'm trying to configure my Django app for production. When I set Debug to False I get "Server Error(500)" When I set debug to true, I get this error instead TemplateSyntaxError at /beginners/ Invalid block tag on line 11: ''style.css''.

Automatic retrying after deadlock in django and mysql setup causes duplicate entry
I'm using solution from Hook available for automatic retry after deadlock in django and mysql setup to handle deadlocks, I thought in case of deadlock exception, the corresponding SQL operation should fail, not changing the status of data in the database. But it seems I was wrong. When I insert some data into a table with unique restrictions, the first try failed because of deadlock, And then execute_wrapper retried automatically, which failed with IntegrityError (1062, "Duplicate entry '96-1160' for key 'xxxxxxxxxxxxx_id_4714853c_uniq'") exception. Can anybody tell me why the first try still changed the data in case of deadlock exception? And any suggestions on how to handle it? Thanks! The execcute_wrapper code listed as below: original = django.db.backends.utils.CursorWrapper.execute def execute_wrapper(*args, **kwargs): attempts = 0 while True: try: return original(*args, **kwargs) except OperationalError as e: code = e.args[0] if attempts == 10 or code != 1213: raise e attempts += 1 time.sleep(0.3) django.db.backends.utils.CursorWrapper.execute = execute_wrapper Thanks! -
Distributed or Central Authorisation in Django Microservices
I'm building a Django rest framework based service which has some complicated permissions. So far, my microservices stack looks like this: /auth/ JWT authentication service /users/ - adding users, adding them to different services /new-service/ - needs authorization Users database is shared by auth and users read-only, and read/write respectively. new-service has no access to this database but the challenges consist of: user can be in multiple groups specific to that service user could have read-only access to one item in one of the groups user could be allowed to create new users with access to one of the groups users have different roles in the service, but we still need to allow for access like the read-only one listed Groups are used not to manage users, but to provide access to things. Like GitLab groups provide access to GitLab projects. If I put all the permissions in the users service, my new service has to talk to that one and it will get chatty. It seems like there has to be a data divide, but I'm not sure exactly where to put it. Conversely, should the django-rest-framework service even have a shadow entry of the user account in it's … -
Django Form Not Posting to SQL
I have a page where an item from a list nested within my form can be favorited, it redirects back to the same page following what should be an update to the database, then it shows a star next to the item. While this should work fine my form doesn't change the DB at all. I am confident it is not the html rendering since when I manually change the field in the admin panel it renders fine. What is causing this to not post? view.py: from django.shortcuts import render, get_object_or_404 from django.http import HttpResponse from django.template import loader from .models import Album, Song # Create your views here. def index(request): all_albums = Album.objects.all() template = loader.get_template('music/index.html') context = {'all_albums' : all_albums,} return render(request, 'music/index.html', context) def detail(request, album_id): album = get_object_or_404(Album, pk=album_id) return render(request, 'music/detail.html', {'album' : album}) def favorite(request, album_id): album = get_object_or_404(Album, pk=album_id) print("favorite stuff happens here") try: selected_song = album.song_set.get(pk=int(request.POST['song'])) except (KeyError, Song.DoesNotExist): return render(request, 'music/detail.html', { 'album' : album, 'error_message': 'Did not select a valid song' }) else: selected_song.favorite = True selected_song.save() return render(request, 'music/detail.html', {'album' : album}) <img src="{{album.album_logo}}"> <h1>{{album.album_title}} </h1> <h2>{{album.artist}} </h2> {% if error_message %} <p><strong> {{error_message}} </strong></p> {% endif %} <form … -
Dropdown Menu Not Working When Implementing with Django
I'm new to working with Django and am running into a problem implementing it into the static site that I've made.

Use 'pass' return value in another function in python
I am using python 3.5. Function1 is : def boolean_key_validation(dictionary, key): data = {} try: dictionary_value = dictionary[key] except KeyError: pass else: if dictionary_value == 'TRUE': data[key] = True elif dictionary_value == 'FALSE': data[key] = False else: raise ValueError("{} value should be either blank or 'TRUE'/'FALSE' only".format(key)) return data[key] # not able to get the 'do_nothing' value here Function 2 is : def read_file(start_date, end_date, dictionary): read_data = {} files = File.objects.all() # ... # read_data['downloaded'] = boolean_key_validation(dictionary, 'downloaded') read_data['integrity'] = boolean_key_validation(dictionary, 'integrity') read_data['validation'] = boolean_key_validation(dictionary, 'validation') return files.filter(**read_data) I want to filter my model 'File' based on the boolean values of 'downloaded', etc. In function1 what I want is that if key is not present in dictionary this function1 should do nothing and my read_data dictionary in function2 should have no value for that key. I have searched for similar problem but those are using 'pass' in conditional statements within some function. -

NOT NULL constraint failed: with my create function
I'm trying to have one view that produces 2 forms and saves them both with one button. I have a good idea on how to accomplish this in an update view so I'm trying to apply the same logic with a create view. Everything seems to be working ok but I'm getting a NOT NUlL constraint failed error. I realize that this error has something to do with my second form probably not being able to find the "carrier" to attach itself too, I just don't know how to go about solving it.

Using instance attributes conditionally determine ModelAdmin inlines? (Django 2.0)
Context: I am writing an app for distributing company policies to users, for them to read and take a test if the policy mandates they do so. The Policy model includes a 'quiz_required' boolean which I would like to use to determine whether the QuizInLine should be included in the inlines of the PolicyAdmin instance. Similar feeds on this issue advise overriding the get_inline_instances and get_form_sets however this produces a Validation Error: ManagementForm data missing error while formset validation. If anyone knows an optimum way of achieving this aim I would be very grateful for the help. Thanks you. models.py class Policy(models.Model): title = models.CharField(max_length = 100)`enter code here` policy = RichTextField() requires_quiz = models.BooleanField('Quiz', default=False) admin.py class QuizInLine(admin.StackedInline): model = Quiz class PolicyAdmin(admin.ModelAdmin): model = Policy fieldsets = [ ('Policy', {'fields': ['title','policy','requires_quiz',]}), ] inlines = [] quiz_inlines = [QuizInLine,] def get_inline_instances(self, request, obj=None): inline_instances = [] if obj.requires_quiz: inlines = self.quiz_inlines else: inlines = self.inlines for inline_class in inlines: inline = inline_class(self.model, self.admin_site) if request: if not (inline.has_add_permission(request) or inline.has_change_permission(request) or inline.has_delete_permission(request)): continue if not inline.has_add_permission(request): inline.max_num = 0 inline_instances.append(inline) return inline_instances def get_formsets(self, request, obj=None): for inline in self.get_inline_instances(request, obj): yield inline.get_formset(request, obj) -
django-admin: change column font to red when if condition is true
I have a vlog that I can preload vlog entries into the db, so that when the date of vlog-published-date is less than the models field of now, the vlog entry will be automatically displayed / published. How can I make the django-admin column of Vlog Date Published font red when the date of the vlog_published_date is greater than now (not yet published)?

Django, GDAL and CircleCI 2
I have a Django app configured with GeoDjango that is failing on CircleCI 2.0 builds with the following error: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library. Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings. However, when I remove 'django.contrib.gis' from DJANGO_APPS in settings.py the build runs successfully. Are there additional steps for configuring GDAL in CircleCI outside of the postgres and GDAL docker images? I (perhaps incorrectly) assumed that GDAL would be found after the docker image was installed.

Using Django Model form with ManyToMany relationship fields
I'm new to development. I have three tables. Table A and Table B have a OneToMany relationship. Where A can have many B's but a B can only have one A. The data from Table A and Table B are already synced. Their relationship table has all the data it needs. Table A and Table B both have a ManyToMany relationship with Table C. I need a form that will link the information in Table C to Tables A and B. I need a form that includes all three tables in a scroll down format. The user would pick an option on table A, depending on their choice on Table A they will get choices on Table B and then all the options in Table C would show up independent of choices A and B. Once the users pick what they want from each scroll down I want the users to be able to submit the form. Once submitted, I need the form to POST relationships, so that it fills the TableA_TableC and TableB_TableC tables in the database. Later on I'll be able to query all the items that Table A has related to Table C, and the items that … -

Different field values for each user

How can I escape underscores in Django's field lookups?
By default, Django cannot support trailing underscores in field names because it messes up field lookups. Unfortunately, I've found myself in a situation where the Postgres table was created without using Django and now I have to do the following: queryset = queryset.filter(**{field + '__icontains': value}) This field could have an underscore. How do I tell Django to ignore the first of the triple underscores and find the field? It clearly knows about the field because it shows it as an option in the error: django.core.exceptions.FieldError: Cannot resolve keyword 'ccc' into field. Choices are: _bbb, aa_a, ccc_ But I have not found any way to force filter to do what I want. Is there a syntax that let's me explicitly specify field name and lookup? -
Django queryset filter max values for list
I'm wondering if there is any way to pass a list to a django queryset and limit to the max/min/latest/oldest value for each item in the list. Basically something like this: serial_list = [2231, 2232, 2233] data_queryset = Data.objects.filter(serial__in=serial_list).latest() I'm fully aware that the above code doesn't work. I'm just trying to illustrate a queryset that would return the .latest() value for each object where the serial is in serial_list. -
