How to Iterate Over a List in Python
I have a simple for loop to iterate over a list of various dates. For each item in the list, I exclude the timezone by taking only the first 10 characters. However, when I pass the object to my template only the first value in the list is being returned for all values. views.py for opportunity in opportunities: temp = opportunity['expectedCloseDate'] time = temp[:10] context { 'time': time } return render(request, 'website', context) template.html <div class="control is-inline-flex"> <input class="input" name="close_date" id="close_date" type="date" value="{{ time }}" disabled> </div> -
Apache crashing from django.contrib class WKBWriter/Reader
I'm running a django application on an apache webserver. This application uses the django.contrib package, specifically django.contrib.gis.geos. Now sometimes this works out well for weeks, only to come crashing down multiple times a day with seemingly no direct correlation to user interaction. The log shows this: Traceback (most recent call last): File "[...]/lib/python3.4/site-packages/django/contrib/gis/ptr.py", line 37, in __del__ NameError: name 'AttributeError' is not defined [...] Exception ignored in: Exception ignored in: Exception ignored in: <bound method _WKBReader.__del__ of <django.contrib.gis.geos.prototypes.io._WKBReader object at 0x7ff4c2f92a58>> I have shortened the huge chain of Exception ignored in:s. After this, apache won't serve any more requests until it is restarted but also still remain active as a daemon. I am not sure which line exactly is responsible for this error. But I found this: https://docs.djangoproject.com/en/2.2/ref/contrib/gis/geos/#creating-a-geometry Under "My logs are filled with GEOS-related errors" it says that this could be avoided by not having any GEOS-Objects created on top level, so I tried to purge those occurrences but it didn't help. Also it seems weird to see NameError: name 'AttributeError' is not defined maybe that can hint to the root of this problem? If you do not know how to instantly solve this, can you give me some … -
save compressed image vs compress image before rendering
I am developing a webapp and need to render images in different sizes, for that I have one option to save images in different sizes and then render whatever needs. It will save time of compression but takes more storage because I need to save 6 different sizes of same image. Another one is compress image before rendering as per size needed, I am not sure but I think it will take more time to process and also takes more memory in ram. Is this make my ram overloaded ?? I want to go with second one but I think its bad. Can anyone tell which method can be more usefull in what case and what can be the technique for this? -
How can I render a plot in Django made on the server via matplotlib?
I'm developing a Django application where I'd like to be able to render a graph that updates when a user checks/unchecks checkbox inputs. I'm having trouble getting the data from the form to my server-side logic, and then rendering the plot (a histogram created via matplotlib) in the view. The data comes from a SQL query in the sqlite database that comes prepackaged in Django. I have verified that the SQL query returns the correct data, and have a script that will create the correct histogram. However, since there are many different options for the user to click to generate the histogram, I'd like to not save each potential histogram as a static file to be served. Ideally, the histogram would update when the user toggles a checkbox. I'm not opposed to using JavaScript/another plotting framework to render the histogram, however I'm not sure how I'd connect that to the database or to the view. Any help would be greatly appreciated! -

Two Models pointing to One Database Table - Redundant Code [Django 2.1]
I'm working on a Django project that have two models on different apps using the same tables on database. The City and State tables are used in both apps.

There is a way to block return back to previous page after logout?
I am using my own authentification because i don't know how to extend django registration app to make me have a model user where user will have his login and password inside the model. when i logout i and click on the background firefox button i get the other page, when i refresh the page i have an session key error what is normal, i want to solve the problem like in the django admin where you can't go back after logout class User(models.Model): name = models.CharField(max_length=25) pwd = models.CharField(max_length=100) created = models.DateTimeField(_('created'), auto_now_add=True) active = models.BooleanField(default=False) def logout(request): from django.shortcuts import redirect for key in list(request.session.keys()): if key == 'id' : del request.session['id'] if key == 'code': del request.session['code'] if key == 'name': del request.session['name'] return redirect('/')
