Arch Nginx Uwsgi no app loaded
I am trying to get django working but uwsgi is having problems loading anything. Most likely do to my ignorance. I would love some help troulble shooting.

Django: Submit Multiple of Same Forms with One Button
I want to improve my page by having one Submit button at the bottom of multiple forms to submit the data to SQL. At the moment, each form has its own submit button and when click on one, it submits all of them at once. I went through different posts and none talked about multiple forms that were all the same. I have one form that consists of Value and Name. I populate a table with this form depending on how many different Name fields there are. In the View, I populate the form as a list containing different instances for each Name. Then in the Template I loop through each item in the form and display it on a row. VIEW for enumeration in enumerationidlist: enumerationdata=Enumeration.objects.get(enumerationid=enumeration) if request.method == 'POST': form = form + [[EditEnumerationForm(request.POST, instance=enumerationdata, read=read, prefix=i),enumerationdata.enumerationid]] if form[i][0].is_valid(): form[i][0].save(commit=True) else: print(form[i][0].errors) else: form = form + [[EditEnumerationForm(instance=enumerationdata, read=read, prefix=i), enumerationdata.enumerationid]] initialList.append(enumerationdata) i = i + 1 Template <tbody> {% csrf_token %} {% for form in forms %} <tr> <td> {% crispy form.0 %} </td> </tr> {% endfor %} </tbody> How can I have just one Submit button displayed to the user that can submit (all at once) … -

Django ManyToMany Teams
I am working on my first application in Django and I don't really know for sure what's the best way to implement the following: Users can be a member of different teams as stated in the following code: class Team(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_lenght=200) administrator = models.OneToOneField(User) members = models.ManyToManyField(User) The user has to be able to switch between teams in the app. This means that one time, the user sees the workspace for team A, and another time, the user sees the workspace for team B. The user is a member of both teams. The URL for both workspaces had to be the same. What's the best way to go about this? -
Post data by URL in many to many field django rest framework
I'm trying to POST with django REST framework, the field is ManyToMany, I kind of have the idea of how to do it but not how to send the data.

How to make Q lookups in django look for multiple values
Currently I have a very simple search option which goes through my pages and looks up through several fields for requested query. If I input a single word in it it works just fine, however if I input multiple words in search query, I get nothing, even if a single page contains all attributes. For example if I search for test admin, I will not get empty query, even though there's a page with title test, with content test and author admin. Is there a way to expand the search to look up each word in search query individually? # Fetch all pages and sort them alphabetically queryset = Page.objects.all().filter(archived=False).order_by("title") # Get search query if applicable query = request.GET.get("q") if query: queryset = queryset.filter( Q(title__icontains=query) | Q(content__icontains=query) | Q(user__username__icontains=query) | Q(user__first_name__icontains=query) | Q(user__last_name__icontains=query) ).distinct() -
Use Django ORM Postgresql regex when the regex is in the database and the value is a string
I understand how to do Postgresql regular expression searches through the Django ORM when I am passing the regular expression. What is the equivalent when the regular expression is in the database table, and I am passing the string? For example, in Django you can do the Postgresql query: INSERT INTO StringValues (val) VALUES ('abc'); SELECT * FROM StringValues WHERE val ~* '^[a-z]{3}$'; With: StringValues.objects.get(val__regex=r'^[a-z]{3}$') How would can you do the following query in Django? INSERT INTO StringValues (val) VALUES ('^[a-z]{3}$'); SELECT * FROM StringValues WHERE 'abc' ~* val; I.E. the regular expression is in the table and I want the row that matches my string. -
Django ManyToMany field related to itself
I have a Django model Groups that I'm trying to relate back to itself, in a ManyToMany field called related_groups. The model changes and the makemigrations script created a new table called group_related_groups (Group was a previously implemented model, with new fields added for relationships). The new model looks like this: class Group(models.Model): """ Model definition of a Group. Groups are a collection of users (i.e. Contacts) that share access to a collection of objects (e.g. Shipments). """ group_id = models.AutoField(primary_key=True) group_name = models.CharField(max_length=100) owner_id = models.ForeignKey('Owner', related_name='groups') category = models.CharField(max_length=30) related_groups = models.ManyToManyField('self', blank='true') What I'm wanting to achieve is the related groups column holds the PKs of associated groups. For example, multiple groups of Students could belong to a single group of Counselors, where the Group model is the establishing factor for all Users. Like: | id | group_name | owner_id | category | ------------------------------------------ | 1 | students1 | 10 | student | | 2 | counselors | 10 | counselor | | 3 | students2 | 10 | student | .... | 7 | students3 | 10 | student | and on the group_related_groups table: | id | from_group_id | to_group_id | ------------------------------------ | 1 | … -

Django image caching with S3
So my app stored users profile photos on S3 and I'm running into an interesting problem. On one particular page we load and display the profile picture ~20 times, and on that page we are using a custom template tag which asks for the users profile_photo.url. My app is configured to use django_storages, and when calling .url my app creates a temp url for the image. When inspecting the page I notice that sometimes the page will make tons of different requests for the same image. The difference between the requests being the key and expiry. Somewhere my app is deciding to not reuse the same temporary URL and I'm not sure what is causing that. So I've got 2 questions: How do I fix the temporary url problem? I think it's related to the use of a templatetag that is used ~10 times on the page users|user_info_as_json How would I implement caching into my app so that images are not always directly served from S3 temp urls. -

Django Sites framework - can I do these things?
I have a general idea of what the Sites framework is, but after much researching, I can't confirm if what I'm trying to achieve is possible. Here's what I want to achieve (simplified). These would be three separate sites - and separate Django projects. Is this possible? Site/Project 1: Customers.ourdomain.com This site manages everything about our customers. There would be a model called Contact which stores all the information about customers (name, address, email, etc.) Have views that a for viewing the Contact model objects, editing their details, etc Site/Project 2: WorkOrders.ourdomain.com This site would manage all things pertaining to Work Orders there would be a WorkOrder model, to create/edit/manage work orders for doing installs and service, etc. In order to create work orders for our customers, the WorkOrder model would need to know about the Customer model from the other site. The work order site doesn't need to edit the customer's data - just needs to have read access of all the customers Site/Project 3: Accounting.ourdomain.com Accounting site for handling all things accounting, such as invoices, accounts receivable, revenue, etc. There would be a bunch of accounting related models, like Invoice, Payment, etc. The Accounting site would need to … -

Specifying Readonly access for Django.db connection object
I have a series of integration-level tests that are being run as a management command in my Django project. These tests are verifying the integrity of a large amount of weather data ingested from external sources into my database. Because I have such a large amount of data, I really have to test against my production database for the tests to be meaningful. What I'm trying to figure out is how I can define a read-only database connection that is specific to that command or connection object. I should also add that these tests can't go through the ORM, so I need to execute raw SQL. The structure of my test looks like this class Command(BaseCommand): help = 'Runs Integration Tests and Query Tests against Prod Database' def handle(self,*args, **options): suite = unittest.TestLoader().loadTestsFromTestCase(TestWeatherModel) ret = unittest.TextTestRunner().run(suite) if(len(ret.failures) != 0): sys.exit(1) else: sys.exit(0) class TestWeatherModel(unittest.TestCase): def testCollectWeatherDataHist(self): wm = WeatherManager() wm.CollectWeatherData() self.assertTrue(wm.weatherData is not None) And the WeatherManager.CollectWeatherData() method would look like this: def CollecWeatherData(self): cur = connection.cursor() cur.execute(<Raw SQL Query>) wm.WeatherData = cur.fetchall() cur.close() I want to somehow idiot-proof this, so that someone else (or me) can't come along later and accidentally write a test that would modify the production … -

I can change the text by changing __unicode__ of the model, but how make it bold for example? in models.py i try the following but form render in with and all other tags as if they just text: def __unicode__(self): u'<b>Name</b>: {}\n<b>Loyal</b>: {}'.format(self.name, self.loyal) my template.html: <form method="post"> {% csrf_token %} {{ form.client|safe}} <br> <input type="submit" value="Save changes" class="btn btn-s btn-success"> </form> doesnt work. Here the picture -

from django.db import models from django.core.urlresolvers import reverse class Gallery(models.Model): Title = models.CharField(max_length=250) Category = models.CharField(max_length=250) Gallery_logo = models.CharField(max_length=1000) def get_absolute_url(self): return reverse('photos:detail', kwargs={'pk', self.pk}) def __str__(self): return self.Title + '_' + self.Gallery_logo class Picture (models.Model): Gallery = models.ForeignKey(Gallery, on_delete=models.CASCADE) Title = models.CharField(max_length=250) Artist = models.CharField(max_length=250) Price = models.CharField(max_length=20) interested = models.BooleanField(default=False) def __str__(self): return self.Title Am getting this error below TypeError at /photos/gallery/add/ _reverse_with_prefix() argument after ** must be a mapping, not set Request Method: POST Request URL: http://127.0.0.1:8000/photos/gallery/add/ Django Version: 1.10.1 Exception Type: TypeError Exception Value: _reverse_with_prefix() argument after ** must be a mapping, not set Exception Location: C:\Users\JK\AppData\Local\Programs\Python\Python35\lib\site-packages\django-1.10.1-py3.5.egg\django\urls\base.py in reverse, line 91 Python Executable: C:\Users\JK\AppData\Local\Programs\Python\Python35\python.exe Python Version: 3.5.2 Python Path: ['C:\Users\JK\PycharmProjects\catalog', 'C:\Users\JK\AppData\Local\Programs\Python\Python35\lib\site-packages\django-1.10.1-py3.5.egg', 'C:\Users\JK\PycharmProjects\catalog', 'C:\Users\JK\AppData\Local\Programs\Python\Python35\python35.zip', 'C:\Users\JK\AppData\Local\Programs\Python\Python35\DLLs', 'C:\Users\JK\AppData\Local\Programs\Python\Python35\lib', 'C:\Users\JK\AppData\Local\Programs\Python\Python35', 'C:\Users\JK\AppData\Local\Programs\Python\Python35\lib\site-packages'] Server time: Fri, 30 Sep 2016 17:15:55 +0300 Again am just a newbie -
Is there a common way of getting the uploaded file across multiple Python frameworks?
Is there a common way of getting the uploaded files in Python just like $_FILES is in PHP? In Django there is request.FILES['fieldid'], in Pyramid request.POST['fieldid'], while in Flask request.files['fieldid']. And all these return a different type of object. However, is there a generic way of getting that in all 3 frameworks? Thanks!
