How to run Django background task only once
I am trying to crop images (thousands of images) on button click bellow is my code! @background(schedule=5) def initialize(): allimages = [] number = 0 if not os.path.exists('thumbnails'): os.makedirs('thumbnails') path = '/Users/shoaibrafa/Data/*.jpg' for image in glob.glob(path): print(image,"=====",number) im = Image.open(image) im.thumbnail((512, 512), Image.ANTIALIAS) im.save("thumbnails/" + os.path.basename(image), "JPEG") number = number + 1 but I face two problems: when clicking the button from the template gives Object of type 'WSGIRequest' is not JSON serializable error! if I call the method initialize() directly when the page loads the background task starts cropping the images, but when the all images are cropped it starts again from beginning cropping the images and continues for ever. What I need is to crop the images and end the background task. bellow is my template: {% extends 'layout.html' %} {% block title %} Login {% endblock %} {% block content %} <a class="btn btn-primary" href="{% url 'home:init'%}">Initialize...</a> {% endblock %} thanks in advance -
Django version upgrade after Python(3.7) upgrade
After python version upgrade to 3.7, I cannot upgrade Django(to v2.0). Django is still tied with the older version of Python(2.7) When I tried, $ pip install --upgrade django I get the following message: Could not fetch URL https://pypi.python.org/simple/django/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661) - skipping Requirement already up-to-date: django in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages Could not fetch URL https://pypi.python.org/simple/pytz/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661) - skipping Requirement already up-to-date: pytz in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pytz-2017.2-py2.7.egg (from django) Do you have any suggestions for this?

ModuleNotFoundError: No module named 'widget_tweaks'

Column Already Exist Error on Django Rest Framework on Heroku Migration
I have updated my model, but I couldn't do the migrations, the problem is: I am getting an error like: column "blah blah" of relation "blah blah blah" already exists The mentioned column should exist in DB, but it shouldn't exist on migration file because I did not do any addition or modification about that model field and it was already successfully created in one of the previous migrations, even used frequently without any error. When I do the migration with --fake, this time it doesn't create the really unexisting field of migration file which is defined with that model update. Deployed on Heroku, it may be caused by rollbacks of code layer, since after rollbacks code gets to older versions but DB stays same. What is the best way without losing any data from production DB? Following is a screenshot of the bash; timezone, endtime and start time fields already exist on model and DB before this migration, created on one of the previous successful migrations Click here to screenshot of Heroku Bash when I try to run migrations Thanks -

Django - save dynamically added forms to DB
I have the following dynamically added forms: The both belong to one forms.modelForm ~ ComponentsForm(), and they were dynamically added on the screen by clicking + button on the screen using jQuery. I want to save these objects to DB by overriding my post() method in CBV. With my current set of codes, clicking submit button prints the following queryDict: <QueryDict: {'csrfmiddlewaretoken': [# foo_token], 'item_description': ['aaaaaaaaa', 'bbbbbbbbb'], 'num_of_jts': ['aaaaaaaaaaa', 'bbbbbbbbb'], 'length': ['aaaaaaaaaaaa', 'bbbbbbbbbb'], 'cum_length': ['aaaaaaaaaaaaa', 'bbbbbbbbbbbbbb'], 'outer_d': ['aaaaaaaaaaaaa', 'bbbbbbbbbbbbbbb'], 'inner_d': ['', ''], 'drift_d': ['', ''], 'od_cplg': ['', ''], 'top_thread': ['', ''], 'air_wght': ['', ''], 'make': ['', ''], 'sn': ['', ''], 'bha_component': ['Submit']}> As you can see, each field list has two items, because there are two dynamically added form instances on the screen. Upon clicking submit button, I want to create new objects if it doesn't already exists in DB, or save changes to DB if it already exists. How can I achieve this? Someone told me to use formsetFactory, but I don't think that's what I want, as these are dynamically added elements, and, it formset won't automatically create new objects in DB for each dynamically added elements. -

Django Forms: Cannot show Validation Error
I have a Django Form where I allow the user to submit a value only if his password matches a predefined password set by me : Pass_matcher Validation works fine, such that if passwords match, value is entered and stored and if not, nothing happens. However I want that if passwords do not match, I show a simple custom warning message. I looked at other SO questions such as here and here, but I can't seem to get it right. Note: If the user enters the correct password I do not want to redirect to another page. forms.py from django import forms class TactForm(forms.Form): password = forms.CharField(widget=forms.PasswordInput( attrs = { 'class' : 'form-control mb-2 mr-sm-2 mb-sm-0', 'placeholder' : 'Enter Password:', 'id' : 'inlineFormInput', 'required' : 'true' } ), required = True, label='Tact Password', max_length=100) tacttime = forms.CharField(widget=forms.TextInput( attrs = { 'class': 'form-control mb-2 mr-sm-2 mb-sm-0', 'placeholder': 'Enter Tact Time:', 'id' : 'inlineFormInput2' } ),label='Tact Time', max_length=100) def clean(self): cleaned_data = super(TactForm,self).clean() password = cleaned_data.get('password') current_tact = cleaned_data.get('tacttime') if password != 'Pass_matcher': print('incorrect') #this prints to console if incorrect raise forms.ValidationError('Incorrect Password') # this does not work else: print('correct') #this prints to console if correct return cleaned_data views.py def details(request): form ... -
Model population using django and python
I am new to Django and planning to design a wizard that will ask the user to populate few values . lets say i have two models Model 1 : col1 , col 2 Model 2 : col1(FK), col2 I display model 1 create view and user enters some values, which then navigates to model 2. In model 2 i get a drop down for col 1 as it is a foreign key. Can i auto populate this value ? One more question, if anyone can get me a lead. I need a screen that has a plus button to populate multiple rows to the model. What i am really looking for is , if the user wants to add additional details he just have to click a button and new row appears , Do i have to do this using java script ? Also i was using a progress bar using bootstrap that shows the remaining screens. -
How hide/show a field upon selection of a radio button in django admin?

This worked only after selecting the status and saving the form. I've given status as radio_fields rather than select boxes since only one of them should be selected. I've tried even by using Jquery as well. Please correct me. admin.js django.jQuery('#id_status').change(function(){ if(django.jQuery('#id_status:selected').text() == 'Accepted') { django.jQuery(".form-row.field-reason_reject").hide(); } else { django.jquery(".form-row.field-reason_reject").show(); } } ); -
Django - Static images do not load, throw 404 error in console
I've been trying to solve this error for a very long time. I have a lot of static images that I am trying to open through my website.

Django: Paginator error: object of type 'User' has no len()
I'm learning to use a paginator as my list are getting really long! I'm having trouble implementing it as I am getting an error.

How to enforce only one running instance of a process in python Django framework?
I have a python Django manage command that should be called upon receiving an input file but this command is not safe for parallel calls. So an input file should be processed only and only when there is no other file being processed. One solution that I have is to use a lock file. Basically, create a lock file at the start of the process and delete it at the end. I'm worried that if the process crashes the lock file won't be deleted and consequently none of the other files would be processed until we manually remove that lock file. The solution doesn't need to be specific for Django or even python, but what is the best practice to enforce that only one instance of this process is being run? -

Implementing Django ForeignKey-like subqueries without ForeignKey
I have a non-ForeignKey ID from an external system that acts as my join key. I'd like to do Django ORM style queries using this ID. My desired query is: results = MyModel.objects.filter(level='M', children__name__contains='SOMETHING') My model looks like this: class MyModel(BaseModel): LEVELS = ( ('I', 'Instance'), ('M', 'Master'), ('J', 'Joined') ) level = models.CharField(max_length=2, choices=LEVELS, default='I') parent = models.ForeignKey('self', blank=True, null=True, related_name='children', on_delete=models.SET_NULL ) master_id = models.CharField(max_length=200) name = models.CharField(max_length=300, blank=True, null=True) This works fine with parent as a field, but parent is redundant with the master_id field: master_id indicates which children belong to which master node. I'd like to get rid of parent (primarily because the dataset is fairly large and setting the parent IDs when importing data takes a long time). The SQL equivalent of what I'm looking for is: SELECT DISTINCT( s_m.master_id ) FROM mytable s_m JOIN mytable s_i ON s_i.level = 'I' and s_m.level='M' AND s_i.master_id == s_m.master_id WHERE s_i.name like '%SOMETHING%'; I believe there's a way to use Manager or QuerySet to enable clean querying of children (in this case, the children's names) within the Django ORM framework, but I can't figure out how. Any pointers would be appreciated. -
