Django use Firebase Database for live messaging
I have a django application. I have 3 models: class ChatSession(models.Model): pass class ChatSessionMember(models.Model): pass class ChatSessionMessage(models.Model): pass These are stored in postgres. But I want them along with the User model saved in Firebase Database. On save and delete I want to make changes respectfully. The reason is because I want to use firebase database only for live messaging. How can I implement this firebase interaction? I looked at pyrebase but it seemed out of date. Its dependencies are too old and is not compatible with my django project. (other dependencies such as stripe use a more up to date request package) -
Is there any similar implementation of python sha1 in Java?
In a spring project I am trying to implement the Django like encryption logic for authentication because it will share the cookie with another python project. The issue I am facing is i am trying to sign the value in java in the same way its done in python. When I call value= hashlib.sha1(b'hello').digest() # the value i am getting is # b'\xaa\xf4\xc6\x1d\xdc\xc5\xe8\xa2\xda\xbe\xde\x0f;H,\xd9\xae\xa9CM' I have written this logic in Java which is not the same value as python. private static void getKey(String key) { try { MessageDigest md = MessageDigest.getInstance("SHA-1"); String result = DatatypeConverter.printHexBinary(md.digest("hello".getBytes())); System.err.println("result===>>>" + result); //the output is 204C417A627048ABE163CAF06434DDAD62FC9BF7 } catch (NoSuchAlgorithmException e) { throw new RuntimeException(e); } } Is there any way I can get the same value in Java ? -

I can't add data to the database through form
I have been working on making a website in which people can post the evaluation of the restaurant they visited. I want users to post data through a form, but I can't make a form page work as I imagined. To speak the detail, the data put in the form isn't added to the database. Please tell me why the system doesn't work. I can't find the data I typed in the form on admin page and "Tabelog/list.html".

Django Compressor: How to manage manifest.json for Offline Compress with multiple servers?
I have setup multiple servers with Django Compressor. So my settings.py AWS_ACCESS_KEY_ID = 'blablabla' AWS_SECRET_ACCESS_KEY = 'blablablabla' AWS_STORAGE_BUCKET_NAME = 'my-bucket-name' AWS_DEFAULT_ACL = 'public-read' AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.s3.amazonaws.com' AWS_S3_OBJECT_PARAMETERS = {'CacheControl': 'max-age=86400'} # s3 static settings AWS_LOCATION = 'static' STATIC_URL = f'https://{AWS_S3_CUSTOM_DOMAIN}/{AWS_LOCATION}/' STATICFILES_STORAGE = 'app_name.storage_backends.CachedS3Boto3Storage' # s3 media settings PUBLIC_MEDIA_LOCATION = 'media' MEDIA_URL = f'https://{AWS_S3_CUSTOM_DOMAIN}/{PUBLIC_MEDIA_LOCATION}/' DEFAULT_FILE_STORAGE = 'app_name.storage_backends.PublicMediaStorage' COMPRESS_ENABLED = True COMPRESS_URL = STATIC_URL COMPRESS_STORAGE = STATICFILES_STORAGE COMPRESS_CSS_FILTERS = [ 'compressor.filters.css_default.CssAbsoluteFilter', 'compressor.filters.cssmin.CSSMinFilter' ] COMPRESS_PARSER = 'compressor.parser.HtmlParser' COMPRESS_OFFLINE = True I got 3 servers. A utility server to execute "manage.py compress" to create a manifest.json file and "collectstatic" to S3 and 2 other application servers have to share the manifest.json file. So What i did is that I made a git repository to update manifest.json. So in utility server, I create one and push to a remote repository and connect to the other 2 application servers to pull the recent manifest.json under CACHE directory. This is what I've done so far to share manifest.json. Is there better approach or idea to handle this problem? -
Django signals can't change global variable
I am making a site where you can have a main goal, and split that into subgoals. I'm trying to grab the deleted instances root parent in the pre_delete function, set that instance to the "goal" variable, and then send that to my post_delete function which updates the entire tree for that "goal" variable. Now my problem arises, How do i get my "goal" variable from my pre_delete to my post_delete I tried setting a global goal value like shown below. but it hits me with " 'str' object has no attribute 'get_descendants' ". So it obviously isn't changing the global variable goal = '' @receiver(pre_delete, sender=Goal) def delete_goal(sender, instance, *args, **kwargs): root = instance.get_root() children = root.get_children() global goal for each in children: if each == instance: goal = each break else: desc = each.get_descendants() if instance in desc: goal = each @receiver(post_delete, sender=Goal) def delete_goal(sender, instance, *args, **kwargs): global goal gd = goal.get_descendants(include_self=False) for goal in gd: parent_progress = goal.parent.progress siblings = goal.get_siblings(include_self=True) result = parent_progress / len(siblings) itself = Goal.objects.filter(pk=goal.pk) itself.update(progress=result) print("Found!") -

What is the correct way to submit Django inline formsets with prefilled data in a modal form
In my Django app, I am querying the database tables using jquery ajax call to fill inline formsets with the json callback data. The following image is a likely situation at the start of the process. The form/formsets are housed in a modal to conserve space. I am wanting to save the user input/s (including the pre-filled values) in the respective tables by submitting the form using ajax. The forms are: class mappedTargModelForm(forms.ModelForm): class Meta: model = mappedTargModel fields = ('mapper_doc_type', 'mapper_name', 'mapper_target_model', 'mapper_long_text') widgets = { 'mapper_doc_type': forms.TextInput(...), 'mapper_name': forms.TextInput(...), 'mapper_target_model': forms.TextInput(...), 'mapper_long_text': forms.Textarea(...), } class mappedTargFieldsForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(mappedTargFieldsForm, self).__init__(*args, **kwargs) self.auto_id = False class Meta: model = mappedTargFields fields = ('mapped_field', 'mapped_field_verb_name', 'mapped_field_col_name', 'mapped_field_fk_table') widgets = { 'mapped_field': forms.TextInput(...), 'mapped_field_verb_name': forms.TextInput(...), 'mapped_field_col_name': forms.TextInput(...), 'mapped_field_fk_table': forms.TextInput(...), } exclude = () CreateMappedTargFieldsFormset = inlineformset_factory( mappedTargModel, mappedTargFields, form=mappedTargFieldsForm, extra=2, can_delete=False) The view as adapted from (https://docs.djangoproject.com/en/2.2/topics/class-based-views/generic-editing/#ajax-example) is shown below: class AjaxableResponseMixin: """ Mixin to add AJAX support to a form.

Django Pagination Keep Current URL Parameters
I am developing a blog website using Django. On the home page, I have a list of posts, and they are viewed using pagination. On the same home page, I also have the functionality to do a text search (i.e. search for posts with a given text). For example, if I search for "hello", then the URL is: http://localhost:8000/?q=hello. Then, I want to go to the second page in the pagination, and I expect the URL to look like this: http://localhost:8000/?q=hello&page=2. However, instead, I get this URL: http://localhost:8000/?page=2. So, basically, when I navigate through pages, I want my pagination to keep the existing "q" parameter in the current URL. The problem is that the "q" parameter is gone when navigating though the pages. How do I fix this? This is my pagination: <div class="pagination"> <span class="step-links"> {% if page.has_previous %} <a href="?page={{ page.previous_page_number }}"><i class="previous fa fa-arrow-left fa-lg"></i></a> {% endif %} <span class="current"> {{ page.number }} of {{ page.paginator.num_pages }} </span> {% if page.has_next %} <a href="?page={{ page.next_page_number }}"><i class="next fa fa-arrow-right fa-lg"></i></a> {% endif %} </span> </div> -

So I tried something like this: <button onclick='update_like({{item.id}}, {{item.name}})'></button>{{ item.name}} But clicking the button just ouputs: Uncaught SyntaxError: Unexpected token 'default' This is a trimmed down version of the full template I'm using: {% extends 'base.html' %} {% load static %} {% block content %} <div class="list"> {% for item in items %} <button onclick='update_like({{item.id}}, {{item.name}})'></button>{{ item.name}} {% endfor %} </div> <script> var count = {}; function update_like(item_id, item_name) { count[item_id] = 1; console.log(count); return; } </script> {% endblock %} -
How to create a Post without a Form Model?
I am trying to figure out more about Post Method so my question's purpose is to understand how to Create a Post without a Form is it possible or not. Here is what I am trying to know how to do. I have a project where I want a user to submit a button without any forms or input from user's side only clicking on the button on the page, after pressing on the button the views are set to change a boolean field so that admin can be notified as an example. Here is what I was thinking about in the model: class Item(models.Model): active = models.BooleanField(default=False) Here is the views.py: class ChangeItemStatus(View): def post(self, *args, **kwargs): if form.is_valid(): item.active = True item.save() messages.success(self.request, 'Item Status has been Change To Active') return redirect("app:template_name") Sorry for the noobish question aiming to have a simplified explanation with this simple example
