Django view fetching data
I have two tables in my database which are relevant for this problem: exercise_state with following fields: id | intensity_level | progress | exercise_id | user_id | current_date | user_rating auth_user with following fields: id | password | last_login | is_superuser | username | first_name | last_name | email | is_staff | is_active | date_joined Right now I am fetching some data in my view as follows: def get_specific_exercise_finish_count(request, exerciseId): # Number of users who completed a specific exercise specific_exercise_finish_count = Exercise_state.objects.filter(exercise_id=exerciseId, intensity_level=7).count() data = {} data['count'] = specific_exercise_finish_count return JSONResponse(data) Now I want to filter those results further for specific set of usernames i.e. usernames those starts with 'yg_' (I have two sets of usernames registered in my system one group starts with 'yg' and the other with 'yg_'). As username is not a field of exercise_state, I am not sure how to proceed. How can I achieve this? -

how to dynamically load css names into django templates without cluttering the view
I have a django app and I retrieve there "theme" value from memcached in views.py and pass it to several templates. What I've achieved is to be able to switch jqueryui theme of various templates system-wide. Here is an example of the template: <link rel="stylesheet" href="{% static "jquery-ui-1.11.4/themes/"%}{{theme}}/jquery-ui.css"> The problem is that I need to retrieve and pass the theme for various view end points and if I forget to do it for one of them, then pf course the theme will not be found. Is there a better way? Maybe using template tags? -

Identifying primary key for a vote table
I am working on a voting table design using Postgres 9.5 (but maybe the question itself is applicable to sql in general). My vote table should be like: ------------------------- object | user | timestamp ------------------------- Where object and user are foreign keys to the ids corresponding to their own tables. I have a problem identifying what actually should be a primary key. I thought at first to make a primary_key(object, user) but since I use django as a server, it just doesn't support multicolumn primary key, I am not sure either about the performance since I may access a row using only one of those 2 columns (i.e. object or user), but the advantage this idea works automatically as a unique key since the same user shouldn't vote twice for the same object. And I don't need any additional indexes. The other idea is to introduce an auto or serial id field, I really don't think of any advantage of using this approach especially when the table gets bigger. I need also to introduce at least a unique_key(object, user) which adds to the computational complexity and data storage. Not even sure about the performance when I select using one of β¦ -
DRF Serializer Nested Field for User Creation
So I have a custom model - Profile, which has a OneToOne relation with a django User object. class Profile(models.Model): user = OneToOneField(User, on_delete=models.CASCADE) profile_type = models.CharField() I want to make a django rest framework serializer which allows for creation of creation and retrieval of a User object's nested attributes as well as the "profile_type" attribute. I want the names to be specified on the POST request as simply as "username", "password", "email", etc. - instead of "profile_username", "profile_password", ... So far I have class ProfileSerializer(serializers.ModelSerializer): username = serializers.CharField(source='profile_user_username') password = serializers.CharField(source='profile_user_password') email = serializers.CharField(source='profile_user_email') class Meta: model = Profile fields = ('id', 'profile_user_username', 'profile_user_password', 'profile_user_email', 'username', 'password', 'email') depth = 2 But - I've been getting an error: ImproperlyConfigured: Field name 'profile_user_username' is not valid for model 'Profile' Am I getting the syntax for nested fields wrong? Or is it something else? -
Django Form with Foreign Key Related Data
I am having some issues with having my form have the user select a value rather than typing it into a text box. I am trying to create a tool checkout transaction, which requires the ToolID, Quantity of the tool checked out, and the PartyID. I would like to let the user be able to see a list of the users First and Last Names rather than select the PartyID. The First and Last Names are required but when I make a form containing those fields it gives me a text box for input. I believe I would rather have the user select the desired user from a drop down option. Any help would be appreciated. Models: class Party(models.Model): PartyID=models.AutoField(primary_key=True, db_column='PartyID') FirstName=models.CharField(max_length=100, null=False) LastName=models.CharField(max_length=100, null=False) PhoneNumber=models.CharField(max_length=25, null=False) Organization=models.CharField(max_length=100, null=True) Deleted=models.BooleanField(default=0) objects=models.Manager() class Meta: managed=True db_table='Party' def __unicode__(self): return str(self.PartyID) def get_absolute_url(self): return reverse("ToolSearch:borrowerUpdate", kwargs={"pk": self.PartyID}) class ToolTransaction(models.Model): CheckOutID=models.AutoField(primary_key=True) ToolID=models.ForeignKey(Tool, db_column='ToolID', on_delete=models.CASCADE,) PartyID=models.ForeignKey(Party, db_column='PartyID', on_delete=models.CASCADE,) Quantity=models.IntegerField(null=False) CheckOutDate=models.DateField(null=False, default=datetime.datetime.now) CheckInDate=models.DateField(null=True) Deleted=models.BooleanField(default=0) objects=ActiveTransactionManager() #objects=models.Manager() class Meta: managed=True db_table='ToolTransaction' ordering=('CheckOutID',) def __unicode__(self): return str(self.CheckOutID) def get_absolute_url(self): return reverse("ToolSearch:toolCheckin", kwargs={"pk": self.CheckOutID}) class Tool(models.Model): ToolID=models.CharField(max_length=100, primary_key = True, unique=True, db_column='ToolID') Quantity=models.IntegerField(null=False) Location=models.CharField(max_length=100, null=False) CategoryID=models.IntegerField(null=True) Deleted=models.BooleanField(default=0) objects=models.Manager() class Meta: managed=True db_table='Tool' def __unicode__(self): return self.ToolID def get_absolute_url(self): β¦ -
Django NoReverseMatch wrong number of arguments
I am getting a NoReverseMatch error after having added a new argument to one of my URLs. Initially, the URL in urlpatterns had been url(r'^(?P<myID>[0-9]+)/go/(?P<otherID>[0-9]+)/$', views.go, name='go') and this worked. I changed it to url(r'^(?P<myID>[0-9]+)/go/(?P<listID>[0-9]+)/(?P<otherID>[0-9]+)/$', views.go, name='go') and updated the function go in views.py to accept another argument (def go(request,myID,listID,otherID):#...). The new argument is not being recognized. When I try to go to my_app/18/go/14/12/ (for example) from my local server it gives the error Reverse for 'go' with arguments '(18, 12)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['frackr/(?P[0-9]+)/go/(?P[0-9]+)/(?P[0-9]+)/$'] So it seems that it does not recognize the listID argument. However, the debugging message says that one of the local variables in the view function is listID with the value of u'14'. So the problem does not seem to be coming from interpreting the URL. I have looked through tons of questions already to try to figure this out, but no one seems to have the same problem. And I realize this is probably a beginner's mistake, but any help would be greatly appreciated. -

How to queue asynch tasks sharing the same background thread
On a Linux server (running Ubuntu), I have an asynchronous task that compresses/encodes videos uploaded by users on a certain Django web application. This task takes around 120s on average. I'm a newbie in the web stack and don't have a lot of experience in it. I'm worrying that if two users simultaneously call the asynch video compression task, one will over-ride the other (this would happen if a single background thread was being used). How does one go about checking whether the above holds true? Secondly, if indeed one task is being blocked by the other, how can I ensure some kind of queuing to happen here? Please give me guidance, preferably with an illustrative example. -

How do I send a JavaScript confirm response over Django to a script to perform operations based on the response?
I'm very very new to Django and I'm currently trying to build a simple To-Do application. I'm currently able to display my To-Do list on the webpage using HTML Tables, but to be able to delete it, I added a new row at the end of every entry called "Delete" with an a href element, on click event sending it to a JS function that pops up a confirmation to the user asking if he actually wants to delete it. I'm storing the response in a variable called response. Now, my question is how do I send this response across django to actually be able to delete the entry? This is what I have done so far and its not working. All help will be appreciated. Thank You. {% for item in task %} <tr> <td>{{ item.task_name }}</td> <td>{{ item.task_priority }}</td> <td>{{ item.task_status }}</td> <td>{{ item.target_date }}</td> <td><a href="" onclick="return delete_function()">Delete</a></td> <p id="delete"></p> </tr> {% endfor %} </table> <script> function delete_function() { var response = confirm("Are you sure you want to delete this item?"); if (response == true){ response.post() } } </script> In my views page, I have this function to handle this post method: def view_task(request): if request.method == β¦ -
AngularJS and CMS
If I built a web app using AngularJS and also want to use Django as a CMS, how do the 2 integrate? For example if I built a site search app using AngularJS how would I integrate the AngularJS searchApp with the Django CMS? AngularJS has UI Router to manage navigation(urls), states, url and query parameters etc. However, Django can manage that as well. So how do you integrate an AngularJS web app with Django CMS. I built both independently and now am not quite sure how to integrate the two? -
Can't delete/modify model permissions
So I have a django model with custom permissions added to it. class TestModel(models.Model): class Meta: permissions = ( ("test_permission1", "Test permission 1"), ("test_permission2", "Test permission 2"), ) I wanted to modify/deleted those existing permissions. So I updated the model to the following: class TestModel(models.Model): class Meta: permissions = ( ("test_permission1", "Updated description"), ) I ran the migration (which detected the changes). But both permissions remain in the database and admin site unchanged / unremoved. Is it not possible to remove/modify a permission once it has been created? (I'm running Django 1.9.1 w/ psql 9.5.3)
