Is there a way to use custom sql queries with various arguments in django?
I'm creating an application that allows a user to filter through millions of records in a database (using dates, post types, etc.). The problem is that the database queries I need to perform are kind of complicated to use Django's ORM so I need to use custom SQL, and I don't have much experience dealing with SQL and this part of Django. If I needed the user specified filters before executing the query, how can I put in custom SQL without knowing how many filters/parameters there might be? And after that, how do I return what I found through that custom query into views so that the results can be displayed on the web page? I've already looked at the Django documentation on raw and custom SQL queries but there isn't a lot of documentation and help on custom SQL queries outside of the Django official documentation, so any help would be appreciated. from django.db import connection def my_custom_sql(self): with connection.cursor() as cursor: cursor.execute("UPDATE bar SET foo = 1 WHERE baz = %s", [self.baz]) cursor.execute("SELECT foo FROM bar WHERE baz = %s", [self.baz]) row = cursor.fetchone() return row The example code here is from the documentation.

Is there a way to use custom template in editor in django admin?
I have an issue with loading custom template file into editor which resides in django admin. I just simply put the file path into CKEDITOR_CONFIGS like so: CKEDITOR_CONFIGS = { 'default': { 'toolbar': [ [...] ], 'templates_files': [ /path/to/template/template.js' ], 'templates': 'template' } } CKEDITOR.addTemplates( 'template', { templates: [ { title: 'BLEBELLBELBE', description: 'A template that defines two columns, each one with a title, and some text.', html: '<table cellspacing="0" cellpadding="0" style="width:100%" border="0">' + '<tr>' + '<td style="width:50%">' + '<h3>Title 1</h3>' + '</td>' + '<td></td>' + '<td style="width:50%">' + '<h3>Title 2</h3>' + '</td>' + '</tr>' + '<tr>' + '<td>' + 'Text 1' + '</td>' + '<td></td>' + '<td>' + 'Text 2' + '</td>' + '</tr>' + '</table>' + '<p>' + 'More text goes here.' + '</p>' } ] } ); Ckeditor is ignoring the file or just throwing and error on browser console that file can't be loaded. What am I doing wrong? -
python : object.__dict__ not showing all attributes
I am trying to print all the attibutes of an object. The purpose is mainly for debugging. I am using the following code: import json print(json.dumps(object.__dict__), indent=4, sort_keys=True, default=str)) It prints the attibutes of the object. But i was checking the list of all properties of the object using dir(object) I found that __dict__ does not show some properties at all which are listed by dir(). I thought of using dir(object) but it only a list of properties without attributes. So i think: `__dict__` has `incomplete` properties but with attirbutes `dir()` has complete list of properties but no attibutes So what is the best way to get a full dictionary of a attibutes of an object so that i can pretty print and see using json.dumps EXAMPLE I am working in a django project. And this is with related to db connection so the example is of a variable names db_con which is of the following object <django.db.backends.postgresql.base.DatabaseWrapper object at 0x7f29dee47a58> __dict__ way import json print(json.dumps(db_con.__dict__), indent=4, sort_keys=True, default=str)) The output is { "_thread_ident": ATTRIBUTE_VALUE "_thread_sharing_count": ATTRIBUTE_VALUE "_thread_sharing_lock": ATTRIBUTE_VALUE "alias": ATTRIBUTE_VALUE "autocommit": ATTRIBUTE_VALUE "client": ATTRIBUTE_VALUE "close_at": ATTRIBUTE_VALUE "closed_in_transaction": ATTRIBUTE_VALUE "commit_on_exit": ATTRIBUTE_VALUE "connection": ATTRIBUTE_VALUE "creation": ATTRIBUTE_VALUE "errors_occurred": ATTRIBUTE_VALUE "execute_wrappers": ATTRIBUTE_VALUE "features": … -

Display all facets that were enabled in previous page
I have a book catalogue which I'm trying to filter search through. Each book falls under topic: ("english" "science" etc) and has a subcategory subcategory: (english: [poetry, plays], science: [chemistry, mechanics]). Each book item also has 2 attributes: book_format ("paperback" ,"hardcover" etc) language Currently the first 2 filters based on topic and subcategory work fine. Under format and language I've found a bug that enables a previously unavailable facet. For example if I chose "science book -> chemistry" the facet_count returns 0 "paperback books" so paperback is unavailable. But when I any other book format in the format field it enables paperbacks. I've debugged and traced the error to oscar.apps.search.facets in munge_field_facet the 'disabled' key is set to True or False based on: 'disabled': count == 0 and not is_faceted_already is_faceted_already is always true, this is because it is dependent on whether any facet in that field has been selected. In my case since I chose "hardcover" in the book_format field all of the facets in that field are enabled. I've checked the docs and various forums on faceting and it seems no one has needed to choose multiple facets whilst keeping previously disabled facets disabled. Here is the problem … -
Reduce 'waiting' time for a GET request to API
I am using Angular for frontend and Django for backend. I am referencing an API with particular graph data I am trying to retrieve. I think I have done it in an efficient way and have tried researching the best ways to do it. But the timings still show 5000-6000ms in waiting. Is this because of the angular to django link before the request is actually sent? I am doing it this way as I have an authorization key I wanted to keep secure in the backend. Code is long and in many files, I will try to explain: -Django get request to retrieve data for 3 graphs, this view also transforms the data into dictionaires and then returns keys and values separately as a response.-This is all coming from the Angular frontend which calls this upon loading the page to view the graphs. I expect/want a quick request and subsequent page loading but the page loads and then the graphs don't load for another few seconds. Any information would be appreciated. -
Upload image while user is filling in the form and validate the uploaded image
I have a django-form where a user can rate a product. To make sure the user has bought the product he has to upload a picture of the invoice. Every invoice has a bar code so what I want to achieve is to analyze the uploaded picture if there is a bar code. This should happen while the user is filling in the other fields of the form. My question is: is this even possible and if yes how can I upload a Image without pressing the submitbutton of the form. I'm in a early prototyp phase of my project so at the moment its enough when the images are only uploaded to a directory without validation. Please let me now if you need more information -

How to save ModelForm fields that are disabled in a template? (Not included in POST request)
I have created a ModelForm and an UpdateView to update the model's values. To simplify, let's say I have formfields A,B and C. My template displays A,B and C, but users can only edit A and B. C is calculated based on the values of A and B (server-side only). I am calculating C in the clean_C method of the modelform. If I set C to 'disabled' in my template, the value is not updated in my model. (I'm guessing this is because it is not included in the POST data?) If I set C to readonly, it saves correctly. Is there a way to still save C while keeping the field disabled? (to clarify, there is nothing in my model/modelform that disables the field, this is only in the template) It looks like the clean_C method runs regardless of the disabled/readonly flag in the template, and the appropriate value is included in the cleaned_data dictionary in the modelform's clean method. I've been digging through the Django source code to figure out why this happens. Can someone point me to where the data from cleaned_data is saved to the ModelForm / Model? -

Django+MySQL - "Authentication plugin 'caching_sha2_password' cannot be loaded"

They suggest changing the engine to mysql.connector.django, however the engine recommended by django is mysqlclient and therefore I would like to use it. Other suggestion were to use naive password instead of sha2. I'd rather not go with this solution for security reasons.

How can i custom a model that insert form data in a list that will show as one field in Django admin?

How to implement log rotation in Django so that the files that are "rolled over" have custom names?
I want to implement logging in Django such that: 1] After a log file size exceeds a certain threshold, a new log file is generated and written to. 2] The name of this new file should be customisable. As an example, the log file name could be current_date_and_time-app_name.log 3] [Optional] The file that has reached the size limit is zipped and stored. How do I go about doing this? I tried using the RotatingFileHandler class but it rewrites old logs and also does not give the flexibility to change the log name. Here is the code that I have written: BASE_DIR_APP = os.path.dirname(os.path.abspath(__file__)) DIR_LOGS = os.path.join(BASE_DIR_APP, 'logs') current_time = datetime.now().strftime("%b-%d-%Y_%H-%M-%S--%f") U_LOGFILE_SIZE = 1 * 1024 U_LOGFILE_COUNT = 2 logging.config.dictConfig({ 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'console': { 'format': '%(name)-12s %(levelname)-8s %(message)s' }, 'file': { 'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s' } }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'console' }, 'file': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'formatter': 'file', 'maxBytes': U_LOGFILE_SIZE, 'backupCount': U_LOGFILE_COUNT, 'filename': os.path.join(DIR_LOGS, current_time + '.log') } }, 'loggers': { '': { 'level': 'DEBUG', 'handlers': ['console', 'file'] } } }) -

Actually migration was created but didn't applied to DB. class TaskType(Base): name = models.CharField(max_length=50) class Task(Base): ... # initially there was only one parameter - TaskType types = models.ManyToManyField(TaskType, blank=True) ...
