Django makemessages not parsing static html in templates directory
I'm trying to generate translation files for my project. I have following set up: settings.py LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True LOCALE_PATHS = ( '/home/------/webapps/django_------/webshop/locale', ) ugettext = lambda s: s LANGUAGES = ( ('en', ugettext('English')), ('de', ugettext('German')), ) TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ '/home/------/webapps/static_------/templates/', ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] And in my test html I have: {% extends "front/base.html" %} {% load i18n %} {% block pagetitle %}{{block.super}} | {{ title }}{% endblock pagetitle %} {% block content %} TRANSLATION TEST {% trans "Testing translate" %} {% endblock content %} After setting that up, I ran ./manage.py makemessages -l de After that, django.po file is created in locale/de/LC_MESSAGES with following content #: webshop/settings.py:131 msgid "English" msgstr "" #: webshop/settings.py:132 msgid "German" msgstr "" So the makemessages did work, but it only parsed .py files for translation and it found two lines in my settings files, where LANGUAGES are stored.

Django many to many field relationship
I have two models . One model is called Company and the other model is called Product. class Company(models.Model): creator=models.ForeignKey(User,unique=True,on_delete=models.CASCADE,related_name="owner",null=True) addbusiness_to_business_list=models.ManyToManyField(User,related_name="business_added") class Product(models.Model): creator=models.ForeignKey(User,null=True) company=models.ForeignKey(Company,null=True ) Login users can add companies to a list called businesslist . I want the login user to be able to view prouducts posted by only companies they have added to their businesslist. I tried going through the official django page, but their explanation was not clear enough, for me to understand this type of relationship querying . Please help me to understand, and to solve this problem. -
Get senders email - Gmail API
Hello! I've got a Django project connected to Gmail API. At this moment I try to say what are user's top senders and top recipients. My general idea is to get an adress from every email (so that adresses may repeat), put them in some kind of a map and then count how many times did this email appear, something like cnt[emails[i]]++. Then sort it and say who is in the top. But the main problem here is with getting those email adresses. -
Job settings form resetting active/deactive attribute on saving changes in views.py
I wrote an active/deactive functionality for my job page. When a user changes some of the attributes of the job and saves the changes, the active/deactive functionality is set back to deactive.

Elastic Beanstalk does not load the Django admin static files
I have static files in a specific app in my project, and I add that route in my config file as my static route for EB, and as I do this EB doesn't load required CSS files for django admin page.

Im having an issue getting attributes from a model showing up in my template correctly. I am querying my User model and trying to show user.id and/or user.username into my template, the following html code, the template renders with the user object showing, and 'None' when I try user.id or user.username. foo.html {% for user in query %} <ul> <li> {{ user }} </li> <!-- WORKS, Shows User Object --> <li> {{ user.id }}</li> <!-- shows NONE --> <li> {{ user.id }}</li> <!-- shows NONE --> </ul> {% endfor %} I am filtering the users that belong to a specific campaign and attempting to show the user details in my template. views.py def campaignDetails(request, **kwargs): form = AddUserForm(request.POST or None) campaign = Campaign.objects.get(id=kwargs['id']) #Query and Filter Users query = User.objects.filter(campaign=campaign) context = {'campaign': campaign, "form": form, 'query': query} return render(request, 'campaigns/campaignDetail.html', context) Model.py class Campaign(models.Model): id = models.AutoField(primary_key=True) campaign_name = models.CharField(unique=True, max_length=25, blank=True) campaign_start = models.DateTimeField(null=True, default=datetime.datetime.now(), blank=True) campaign_end = models.DateTimeField(null=True, blank=True) class User(models.Model): id = models.AutoField(primary_key=True, null=False) campaign = models.ForeignKey(Campaign, on_delete=models.CASCADE, null=True, blank=True) username = models.CharField(max_length=25, null=True) -
Django: writing text from uploaded file to text field
I have the following model: class Clean(models.Model): name = models.CharField(max_length=100) cv = models.TextField(max_length=10000) cvfile = models.FileField() I am trying to write the contents of cvfile to cv when the user submits the name and file from the form. I'm sure this can be done as the file and text field will be in the same object. The file will always be .txt so I assume a simple .read() can be performed. Should I have a function that the form calls to perform this? If so how can this be done? def writeCV(self): get_text = cvfile.open().read() #write to cv field somehow return self.cv I am using django 1.9 -
Django tests taking a long time to start
I'm running tests on a django App called stats which uses a Postgre database. The project keeps all tests in a folder ./stats/tests/. When I run a test i.e. python manage.py test stats.tests.test_dataGeneration, several minutes of nothing pass where the text cursor in my command line just blinks. At this early stage I cannot even use a keyboard interrupt to instantly stop the test (keyboard interrupt takes at least 30 seconds to register). Eventually, after several minutes I see the Creating test database for alias 'default' ('test_statsdb')... message which creates the database for testing. From this point the tests always complete in less than 10 seconds (as in django outputs Ran XX tests in 5.00s). I don't know or understand why the tests take so long to start, or what is exactly being executed in the first few minutes. A few days ago I had no issues testing the app. Using --keepdb to recycle the test database between test runs does not noticeably improve the time that running tests takes. I was hoping someone could shed some light on what is happeneing. Example output of test results when i run them with verbosity=2 for extra details: >python manage.py test stats.tests.test_dataGeneration … -
Django DRF create user
I am trying to serialize a CreateUserSerializer(ModelSerializer) My code is as follows.

Django debug page shows up even with DEBUG set to `False` in nginx on server
I set up my Django project on a Linode server running Ubuntu 14.04, using this guide for help: https://www.linode.com/docs/web-servers/nginx/deploy-django-applications-using-uwsgi-and-nginx-on-ubuntu-14-04/. I have DEBUG set to False in both settings.py and local_settings.py. When I open a Python shell with python manage.py shell and run from django.conf import settings; print settings.DEBUG, False prints to the terminal. If I run python manage.py runserver 0.0.0.0:8080 in a virtual environmnt and navigate to my.server.ip:8080/path-that-does-not-exist, it takes me to a page that says "Page not found." Why does debug continue to appear when I navigate my browser to a bad request on my Linode server? -

Django - A link that will update database row before leaving site
I'm quite new to Python development and working on a specific project. I have a list of 'action items' that people can 'claim'. So I created a Model that has all of the information about the action item, including a BooleanField called is_claimed which is defaulted to False. I'm printing out all of the action items in a table, of which the last column is a link to an external site (which is also a URLField in my model). I want to have that last table cell be something like this: <a href="{{ action_item.url }}">Claim and Complete Action Item</a> When someone clicks that URL, I need to update the database to show is_claimed=True. Any ideas or help? Sorry if this question is too simplistic. Learning a lot but need some expert help! Thanks -

Perform 3 tasks in a single api call
My current api call flow from my client is as follows: Send data to brand endpoint, retrieve recently inserted id, assign to userData.brand Send data to user endpoint, retrieve recently inserted id, assign to userData.user Send both values to userBrand endpoint This seems like a costly process, so I am thinking of consolidating all the requests into one, but I am not sure how to process it from the server side. I know that I can just use one endpoint, but I don't know to how to use all the serializers/views against one endpoint. So on the client side, this is what I have: In brand.js AdsomaService.registerUser(vm.userData).then(function(data) { vm.successMessage = data.message; vm.userBrandData.user = data.id; }, function error(data) { $log.info(data); vm.errorMessage = data; errorCount++; }); AdsomaService.registerUserBrand(vm.userBrandData).then(function(data) { vm.successMessage = data.message; }, function error(data) { $log.info(data); vm.errorMessage = data; errorCount++; }); if(errorCount > 0) { vm.message = vm.errorMessage; angular.element('#errorMessage').appendTo('body').modal('show'); } else if(errorCount === 0) { vm.message = vm.successMessage; angular.element('#successMessage').appendTo('body').modal('show'); } In adsoma.js function registerUser(userData) { var url = envService.read('apiUrl') + '/user_signup/'; var dataJSON = { email: userData.email, password: userData.password, account_type: userData.accountType }; var req = { method: 'POST', url: url, headers: {'Content-Type': 'application/x-www-form-urlencoded'}, data: $httpParamSerializerJQLike(dataJSON) }; return ($http(req).then(handleSuccess, handleError)); } function registerBrand(brandData) … -

Removing Images, Image_titles, Image_description from a post with multiple images
Hi Djangonauts, I have a post with multiple images. I was able to make the post_create view for this post. Also I was able to create a partially working post_edit view. When I say partially working, what I mean is.. example: If my post has 5 images. I can replace all 5 of my images with alternate 5 images. I can also add more images so my post has 6 or 7 images. what I cannot do is remove any existing images. What makes this a bit more complicated is that the extra images have their own image_title and image_description to them below are my models.py so you know what exactly is going on class Post(models.Model): user = models.ForeignKey(User, related_name='posts') title = models.CharField(max_length=250, unique=True) slug = models.SlugField(allow_unicode=True, unique=True) message = models.TextField() post_image = models.ImageField() def get_absolute_url(self): return reverse('posts:single', kwargs={'username': self.user.username, 'slug': self.slug}) class Prep (models.Model): #(Images) post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='post_prep') image = models.ImageField(upload_to='images/', blank=True, null=True, default='') image_title = models.CharField(max_length=100, default='') image_description = models.CharField(max_length=250, default='') def __str__(self): return self.post.title + " Image" Below is my post_create view which is working perfectly @login_required def post_create(request): ImageFormSet = modelformset_factory(Prep, fields=('image', 'image_title', 'image_description'), extra=7) if request.method == "POST": form = PostForm(request.POST or None, … -
Django : Factorize HTML code
I am building a website about movies, actors etc... And I need your advices in order to factorize my templates. Currently I have 5 templates : base.html : containing header menu, footer [located in the master templates folder] actors : display all the actors (extends base.html) [located in the templates folder from the application 'movie-library'] actor : display one actor and all tbe movies he played in (extends base.html) [located in the templates folder from the application 'movie-library'] movies : display all the movies (extends base.html) [located in the templates folder from the application 'movie-library'] movie : display one movie (extends base.html) [located in the templates folder from the application 'movie-library'] So, in actor.html and movies.html it's the same HTML code to display one movie. And in actors.html and movies.html I have the same HTML to display a pagination bar. How could I factorize those to piece of code ? Thank you. -

Django - access ManyToManyField right after object was saved
I need to notify users by email, when MyModel object is created. I need to let them know all attributes of this object including ManyToManyFields. class MyModel(models.Model): charfield = CharField(...) manytomany = ManyToManyField('AnotherModel'....) def to_email(self): return self.charfield + '\n' + ','.join(self.manytomany.all()) def notify_users(self): send_mail_to_all_users(message=self.to_email()) The first thing I tried was to override save function: def save(self, **kwargs): created = not bool(self.pk) super(Dopyt, self).save(**kwargs) if created: self.notify_users() Which doesn't work (manytomany appears to be empty QuerySet) probably because transaction haven't been commited yet. So I tried post_save signal with same result - empty QuerySet. I can't use m2mchanged signal because: manytomany can be None I need to notify users only if object was created, not when it's modified Do you know how to solve this? Is there some elegant way? -
