Django: How to assign a template variable to a views variable?
I have the following code in Javascript, which takes a user's name from a drop down list and changes his/her "is_active" attribute to true: function acceptFunction(){ var select = document.getElementById("dropdown"); var elementText= select.options[select.selectedIndex].text; var lbl = document.getElementById("lbl"); {% for user in list %} {% ifequal user.username strUser %} {{ user.is_active }}=true; {% endifequal %} {% endfor %} var i; for (i=0;i<select.length; i++) { if (select.options[i].text==elementText) { lbl.textContent=select.options[0].text; select.remove(i); } } } The "select" variable is a drop down list, the "elementText" is the list's element selected the current time by the website user and the "lbl" variable is a label used to print the selected element. In views.py I have the following: def acceptUserRequest(request): list = User.objects.all() strUser='' return render(request, 'acceptUserRequest.html', {'list': list, 'strUser':strUser}) and I am having difficulty in assigning the value of elementText in strUser. Is there a way in Django to accomplish this? Thank you. -

django mulitple dynamic forms
I'm recently building a Fitness Web App with django. I new to web development and django. Therefor I created a page where a Member can create his own training plan. I like to store the plan in my database, but that's the point where it gets difficult. When the user visits the page 'add workout', he should have to enter a name for the workout. Next he can search for exercises in my DB, this works perfectly fine. Than he hast to set his sets, reps and weight for the exercise befor it is added to the training plan. image of my webpage Here are my models: class Exercise(models.Model): name = models.CharField(unique=True, max_length=150) difficultLevel = models.IntegerField() link = models.CharField(unique=True, max_length=1000, blank=True) description = models.CharField(max_length=5000, blank=True) muscleGroup1 = models.CharField(max_length=150, blank=True) muscleGroup2 = models.CharField(max_length=150, blank=True) muscleGroup3 = models.CharField(max_length=150, blank=True) equipment1 = models.CharField(max_length=150, blank=True) equipment2 = models.CharField(max_length=150, blank=True) equipment3 = models.CharField(max_length=150, blank=True) class TrainingPlan(models.Model): member = models.ForeignKey(Member) name = models.CharField(max_length=150) lastChange = models.DateField(auto_now=True) class MemberExercise(models.Model): member = models.ForeignKey(Member) exercise = models.ForeignKey(Exercise) trainingPlan = models.ForeignKey(TrainingPlan) sets = models.IntegerField(null=True) reps = models.IntegerField(null=True) weight = models.FloatField(null=True) # in kg duration = models.IntegerField(null=True) # in sec The results of the search are just of type Exercise, the … -
How to change Django admin filter option names
I have a list of vehicles in my Django app that can be filtered in the admin by the vehicle's make field. The make field is a Charfield with choices from a list of tuples, so the values are stored in the database as abbreviations. In my model admin class, I have a list filter for the make, but the options are just all the abbreviations, JD, KU, etc. How can I override this, so it shows its verbose name from the tuple it was assigned to, rather than it's abbreviation ? Model Admin Class class InventoryAdmin(admin.ModelAdmin): model = Inventory list_display = ['id', 'inv_stock_no', 'status', 'inv_type', 'inv_subtype', 'make', 'full_make_name', 'model_no', 'date_added_to_inv', 'image_count', 'is_featured', 'list_price'] search_fields = ['inv_stock_no', 'inv_type__name', 'inv_subtype__name', 'model_no', 'id'] list_filter = ['status', 'inv_type', 'make', 'description', ('make', custom_titled_filter('My Custom Title'))] raw_id_fields = ['parent', ] inlines = [InventoryImageInline, InventoryFeatureInline] fieldsets = ( (None, { 'classes': ('full-width', 'suit-tab', 'suit-tab-general'), 'fields': ( 'inv_stock_no', 'description', 'status', 'condition', 'location', 'inv_type', 'inv_subtype', 'make', 'model_no', 'model_year', 'hours', 'serial_no', 'original_cost', 'original_price', 'list_price', 'general_info', 'is_featured', 'date_added_to_inv', 'date_modified_in_inv' ) }), ) suit_form_tabs = (('general', 'General'), ('images', 'Images'), ('features', 'Features')) def full_make_name(self, obj): return obj.make.name class Media: js = [ '//tinymce.cachefly.net/4.2/tinymce.min.js', '/static/admin_js/tinymce_init.js' ] Inventory Model makes_list = ( ('KU', 'Kubota'), … -
Why isn't celery periodic task working?
I'm trying to create a periodic task within a Django app. I added this to my settings.py: from datetime import timedelta CELERYBEAT_SCHEDULE = { 'get_checkins': { 'task': 'api.tasks.get_checkins', 'schedule': timedelta(seconds=1) } } And created a celery.py file in my project folder: from __future__ import absolute_import, unicode_literals import os from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'testproject.settings') app = Celery('testproject') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() Inside my app, called api, I made a tasks.py file: from celery import shared_task @shared_task def get_checkins(): print('hello from get checkins') I'm running the worker and beat with celery -A testproject worker --beat -l info It starts up fine and I can see the task is registered under [tasks], but I don't see any jobs getting logged. Should be one per second. Can anyone tell why this isn't executing? -
Swagger boolean parameter value True/False instead of true/false and django_filters
Swagger UI submits boolean params in 'true/false' form, while django filter boolean field expects True/False (uppercase). Therefore when I query through swagger, the field is_published has no effect. {{api_url}}/api/v1/games/?limit=10&offset=0&is_published=true {{api_url}}/api/v1/games/?limit=10&offset=0&is_published=false Filter field is defined as is_published = BooleanFilter(name='versions__is_published') full definition class GameFilter(FilterSet): """Custom filter for ``GameViewSet``.

In Django with Postgresql 9.6 how to sort case and accent insensitive?
What I would like is the equivalent of using utf8_unicode_ci in MySQL. So if I have those strings (default sort order with Postgresql): Barn Bubble Bœuf beef boulette bémol I wish they would be sorted like this (as with utf8_unicode_ci in MySQL): Barn beef bémol Bœuf boulette Bubble This kind of sort is case insensitive, accent insensitive and ligatures are converted to multiple characters. I know about unaccent and lower in Postgresql but I have no idea how to use them from Django. Possible solutions with Django/Postgresql: Add new column only for sorting with data normalized (lower, unaccent). Add an index (like in this answer), but I'm not sure how it will work with Django? I don't think Full Text Search or Trigram could help me here because I'm not necessarily doing searches base on text but I need to get the good sort order. Ideally queries should be fast so using another indexed column looks like a good avenue. But I wish to find a solution that I don't need to implement for every exisiting text column in my DB, that is easy to maintain, etc. Is there a best practice to do that? -

Django Rest Framework Uploaded File Url
Django rest framework automatically generates urls for uploaded files. However, the url it automatically generates doesn't actually point to where the file is stored. For example, I upload a file to my api named example.txt and this is what the object in my database looks like after the upload: { name: "John Doe", bio: "localhost:8000/api/users/static/example.txt" } My static directory is located in the root directory so the file actually lives and can be accessed at localhost:8000/static/example.txt. The automatically generated url returns a 404. How can I overwrite the automatically generated url to be the correct one? Here's what my model looks like: class User(models.Model): name = models.CharField(primary_key=True, max_length=30) bio = models.FileField(null=True, blank=True, upload_to='static') -

How do I annotate count of field occurances in another model?
Using Django 1.11. These are my models: class UserPromoCode(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name="user_promo_code") promo_code = models.ForeignKey(PromoCode, related_name="user_promo_code") class PromoCode(models.Model): code = models.CharField(max_length=20) @property def assigned_times(self): # how many promo code with same code assigned on users return UserPromoCode.objects.filter(promo_code__code=self.code).count() I'm trying to optimize DB requests when taking a list of promocodes with their assigned_times counts. Is it possible to put it into annotation? I mean something like PromoCode.objects.annontate(assigned_times=Count(???)) -
Multiple inheritance in Django Template
In some of my templates, I have to use some specific JS libraries. For the libraries that I use the most, I defined a helper template like this: {# general/libs/js_lib.html #} <script type="text/javascript" charset="utf8" src="https://cdn...js_lib.versionX.min.js"></script> And then in my page's template I include this template (suppose that base.html defines {% block body %}, {% block css %} and {% block javascript %}): {# page.html #} {% extends 'base.html' %} {% block body %} ... {% endblock body %} {% block javascript %} {{ block.super }} {% include 'general/libs/js_lib.html' %} {% endblock javascript%} I do this so that whenever I update the library's version, it immediately updates it on every page that uses it. This would also make the change easier if I then choose to serve it myself instead of using CDN. The problem is that sometimes the library also needs a specific CSS file. For the time being, I just include it in the same js_lib.html template, but this means that I have a <link> tag that's not in the <head>. What I would like to do is define a sort of 'template mixin', so that my page's template extends a base.html, but also implements my js_lib mixin. I'm … -

I have been working with VS2015 on a django project for awhile now.

Django - handling form without the form model
I wish to handle a form I created with HTML in django, but I can't find the correct way to get the value from the inputs. This is my HTML form: <form action="" class="form-inline" method="post"> {% csrf_token %} <!-- malfunction description --> <label class="requiredField" for="malfunctionDescription">תאור התקלה</label> <br/> <textarea class="form-control" style="width: 100%; margin-bottom: 3px" id="malfunctionDescription" name="malfunctionDescription" rows="5"> </textarea> </form> And this is my view.py which is unfortunately empty: def index(request): return render(request, 'resources-management/home.html') The main goal for me is to get this information from the form and create a new object that will push it to the data base. If I understand correctly to create this object I need to do something like: Object_name.object.create(information=information) But I don't know how to get the information, I need something like request.form['name'] in Flask Thanks! -
Django: 0 and Null first when filter_by used in Ascending and Descending starts with lowest first and then highest
I created a leaderboard using Django. Except It doesn't. It displays the information except for one thing. Empty Fields and those with 0 get first. If it's set in Ascending Order. Left by Default But for Descending Null and 0 get last but a first number is 4 and then the highest numbers. Used a - on it. Why? This doesn't make sense or I'm a moron This is my views.py: Ascending participants = Participant.objects.order_by('totalpoints') Descending participants = Participant.objects.order_by('-totalpoints') Any Help would be appreciated! -
is there an easier way to either create or re-write exist object? django
I know in django we can create an object model easily by using something like this AbcModel.objects.create(field1='a', field2='b') But this would create the object even if it already exists. I know I can use filter() then use the exist() to check if the object already exist then decide to update or create. But is there an easier and faster way to do this? Since, there is get_or_create so I am curious if there's something similar. Thanks in advance -
Extending Django User model - form population errors
I'm extending Django's (v1.9) built-in User model with Player class, to add some extra properties. class Player(models.Model): TIMEZONES=() user = models.OneToOneField(User, on_delete=models.CASCADE) ... (player-specific properties here) time_zone = models.CharField(max_length=255, choices=PRETTY_TIMEZONE_CHOICES, blank=True, null=True,) When creating users from Django admin panel, I don't always need to create players, so sometimes only User gets created. As a result, Player and User IDs don't exactly match. Turns out that this leads to a problem when populating ModelForms of models that are linked to Player, like this one: class City(models.Model): player = models.ForeignKey(Player, on_delete=models.CASCADE) name = models.CharField(max_length = 100) x_coord = models.SmallIntegerField() y_coord = models.SmallIntegerField() region = models.CharField(max_length = 100) def __unicode__(self): return str(self.player) + "-" + str(self.name) class Meta: db_table = 'cities' class CityForm(ModelForm): class Meta: model = City fields = ( 'name', 'player', 'x_coord', 'y_coord', 'region') In views.py the modelForm is created from POST data: form = CityForm(request.POST) Player is rendered as a hidden field in the UI, and when User ID and Player ID match it gets populated correctly; however when they are different, Player field is empty and the form does not validate. I have no problem getting Player ID from request.user, and I could fix up the player ID before … -
Download site-packages from Heroku
I've been asked to make some amendments to a Python / Django application on Heroku. I've cloned the site and tried to run pip install -r requirements.txt to set it up locally but a number of the apps will not install. 4 of these are because pip cannot find the right versions (and that seems to be because they're from 2012) and some are because they appear to be previous supplier specific and so were probably not installed locally. My question is, can I get at the site-packages directory and download everything into my virtual environment (and will that even work - I think not but have promised to try) or is there a better way? -
How to rate limit Celery tasks by task name?
I'm using Celery to process asynchronous tasks from a Django app. Most tasks are short and run in a few seconds, but I have one task that can take a few hours. Due to processing restrictions on my server, Celery is configured to only run 2 tasks at once. That means if someone launches two my these long-running tasks, it effectively blocks all other Celery processing site wide for several hours. Is there any way to configure Celery so it only processes one type of task no more than one at a time? Something like: @task(max_running_instances=1) def my_really_long_task(): for i in range(1000000000): time.sleep(6000) Note, I don't want to cancel all other launches of my_really_long_task. I just don't want them to start right away, and only begin once all other tasks of the same name finish. -
Django Migrate Fails due to Type Conflict
Here is my Chapter model code: class Chapter(models.Model): name = models.CharField(max_length=180) is_canon = models.BooleanField(default=True) series_id = models.ForeignKey('Series', on_delete=models.CASCADE, blank=True, null=True) def __str__(self): return self.name When running python3 manage.py makemigrations, I provided a one off value of 'NULL' for the new field series_id in order to populate existing rows, when I should have backed out and added blank=True, null=True to the definition, as it is now in the code provided above. So, now, I want to run python3 manage.py migrate, but of course the migration fails because I've got a bunch of 'NULL' strings in places where django is expecting actual NULL values/integer values. How to I get rid of those 'NULL' values and reset things so I can migrate? Thank you for your time. -
Make a better code
from crispy_forms_materialize.layout import Div and the code is def get_submit(title=None, button=None): if title is None: title = LABEL_CREATE return Div( Div( Append the line here --> HTML('<a href="/accounts/signin/" class="btn btn-primary">%s</a>'% LABEL_SIGNIN), Submit('submit', title, css_class='white-text'), css_class="right-align"), css_class="card-action") You could see the line HTML('<a href="/accounts/signin/" class="btn btn-primary">%s</a>'% LABEL_SIGNIN), in the above code. This line is optional in fact. I would like to modify this code in such a way if button is not None, then it will append that line in the Div method. My problem is not the if statement, my problem is to append this line if the condition is respected. How could I do that? Thanks in advance! P.S. Please tell me if my question is unclear. To be clear, what I want is def get_submit(title=None, title2=None): if title is None: title = LABEL_CREATE if title2 != None: return Div( Div( HTML('<a href="/accounts/signin/" class="btn btn-primary">%s</a>'% LABEL_SIGNIN), Submit('submit', title, css_class='white-text'), css_class="right-align"), css_class="card-action") else: return Div( Div( Submit('submit', title, css_class='white-text'), css_class="right-align"), css_class="card-action") This worked, but it is a very bad programming to repeat the code. That's why I wanted to just add a line in the code. I use this code with get_submit(title=LABEL_SIGNUP, button=LABEL_SIGNIN), -
