Get non-hashed urls when using Django's ManifestStaticFilesStorage
When using ManifestStaticFilesStorage the static template function always returns the 'hashed' file name (when DEBUG=False). Is there any way to get the non-hashed regular file name in the template? It seems odd that there's no obvious way since collectstatic always includes both hashed and non-hashed files, but the non-hashed ones would never be used. I'm guessing what I need to do is create my own templatetag, but was wondering if I missed something. -
Django Default image for ImageField using Google Drive Storage
I'm using an ImageField to store the images of my models and implementing Google Drive Storage as a backend to store the data. However, in some cases it is necessary to load a predetermined image. So try to assign a static image from the model but it did not work from django.db import models from gdstorage.storage import GoogleDriveStorage # Define Google Drive Storage gd_storage = GoogleDriveStorage () class Album (models.Model): name = models.CharField (max_length = 250) cover = models.ImageField (upload_to='images/', default='static/no_cover.jpg', storage=gd_storage) Then I solve it from the template in the following way but I do not think it is the most ideal. {% if album.cover.url == None%} <img class="card-img-top" src="{% static 'no_cover.jpg'%}"> {% else%} <img class="card-img-top" src="{{album.cover.url}}"> {% endif%} Any idea how to load the static image? -
Variables not displaying on Django template
I have added variables to my Django views and I am trying to call them on my template. I have researched several related questions and I understand that I needed to add a context, which I believe I have done. I am slightly confused by the use of render(), is this required when using generic views? Here is an example of my view: class SubgenView(generic.TemplateView): template_name = 'projects/subgen.html' context_object_name = 'subject_line_gen' all = { "first": ['Save up','New in','Huge savings',], "cat": ['trainers','suits','onesies'], "brand": ['one', 'two', 'three'], "third": ['at crazy prices', 'in colours galore'], "end": ['click now!', 'come and get it!'] } first = random.choice(all['first']) def create_subject_parts(self): first = random.choice(all['first']) test = 'hi' return first Adding {{ first }} or {{ test }} to my template yields nothing, what am I missing? -
Static files not loading (Django 1.11)
I am trying to set up a development version of a Django Rest (1.11) application on a mac. I have run the python manage.py collectstatic command and this resulted in the files being copied into a 'static' folder. However when I run the application (python manage.py runserver) none of the static files load in the browser (no css). The Network tab shows the status of the static files as 404. My settings.py file has the following: STATIC_URL = '/static/' STATIC_ROOT = BASE_DIR + '/abba_rest/static/' Appreciate any advice on how to debug this issue. -

Integrating python-social-auth users with existing app users
I have a Django app that already has existing users and now I'm trying to implement social authentication using auth0. When signing in with social authentication, I see that a new record is created in both social_auth_usersocialauth and the auth_user tables in the db. These new records are created regardless of whether a user with the same username is already present in auth_user. My understanding is that python-social-auth FIRST checks in social_auth_usersocialauth table if there's a user with the same username and THEN creates a user in auth_user accordingly. How can I make it first check in the auth_user table if there's already an entry with the same username and if so create a new user ONLY in the social_auth_usersocialauth table and associate it to the one in auth_user. https://python-social-auth-docs.readthedocs.io/en/latest/pipeline.html -

Get database column if 2 other things match in DB row
I am trying to create a view for when users want to download their file. I have a HTML button that says download, and when that is clicked I want to redirect it to my view to do some stuff. Now each download button has a unique path to the file which I also have saved in my database. So in my views I need to check if a row has some columns that matches the logged in user (request.user), and a TaskID which is in my HTML table where the download button also is located -> And if those matches then grab the column containing the OutputPath. How would I construct such a query? <div class="tasks-finished"> <h1>Finished tasks</h1> </div> <div class="tasks-list"> <table> <tr> <th>Name</th> <th>Task ID</th> <th>Status</th> </tr> {% for item in query_finished %} <tr> <td>{{ item.TaskNavn }}</td> <td>{{ item.TaskID }}</td> <td><a href="{{ myDownloadView }}">Download</a> </tr> {% endfor %} </table> -
Performing full text search on more than one field from model (Django 2.1)
I want to perform full text search on 2 fields from my model. Here is my current code: if 'keyword' in request.GET: search_term = request.GET['keyword'] vector = SearchVector('Title', weight='A') + SearchVector('Content', weight='B') articles = articles.annotate(similarity=TrigramSimilarity(vector, search_term),).filter(similarity__gt=0.01).order_by('-similarity') This code returns the error message "function similarity(tsvector, unknown) does not exist". I assume this is because my code isn't how you would perform search on more than 1 field. What's the proper way of searching in more than one field? -

Iterating over pandas dataframe when you don't know the indexes or number of columns
I'm sending a pandas dataframe to a Django template using to_html(). I'm adding classes as well as working with the css to make my resulting table look the way I want it. df.to_html(classes="table table-bordered table-sm g-font-secondary") But now I need to add a class "g-bg-white" to tags based on the content of the data cell: <td class="g-bg-white">item needs white background</td> In addition I need to add a couple header rows at the top of the table: <tr> <td colspan="2" class="no-line"></td> <th colspan="x" class="g-bg-primary text-center no-line">LABEL</th> </tr> <tr> <td colspan="2" class="no-line"></td> <th scope="col">1</th><th scope="col">2</th><th scope="col">3</th><th scope="col">4</th><th scope="col">5</th><th scope="col">6</th> </tr> As well as a tag into the first row of data: <th scope="row" rowspan="y" class="g-bg-primary text-center">LABEL</th> My sense is that this level of manipulation requires that I iterate through the dataframe on the template. The issue there is that the Django template does not know the indexes or the number of columns in each table. So I don't know that this would work for me: for index, row in df.iterrows(): print(row['c1'], row['c2']) -
