Django queryset optimization with prefetch_related
I'm working on a project based on Django 1.11, and I'm trying to optimize database access with prefetch_related, here is what I'm facing: I have some model definitions(simplified): class D(models.Model): foo = models.IntegerField() class A(models.Model): foo = models.FloatField() class B(models.Model): a = models.ForeignKey(A) d = models.ForeignKey(D, related_name='bs') # Some fields are identical to C foo = models.CharField() # A special field bar1 = models.FileField() class C(models.Model): a = models.ForeignKey(A) d = models.ForeignKey(D, related_name='cs') # Some fields are identical to B foo = models.CharField() # A special field bar2 = models.FloatField() I want to retrieve some objects of D, when retrieving them from DB, I want to retrieve them along with all related(directly) B objects and C objects and related(indirectly) A objects, Currently I'm using: >>> qs = D.objects.filter(foo=1) # some queryset of D >>> qs = qs.prefetch_related('bs__a', 'cs__a') The performance is ok(compared with no prefetch_related), I see raw SQL queries from django-debug-toolbar and it looks like Django breaks the query into something like(psuedo SQL): select * from D select * from B where `d`.`id` in (ids from D) select * from A where `A`.`id` in (ids from B) ---> first time select * from C where `d`.`id` in (ids from … -
Django: m2m select with thumbnails
I am new to Django development and trying to build my own site with a portfolio of my work and a blog. The portfolio part of my site has posts that include a variable number of images to use as thumbnails. In Django admin, I would like to be able to see thumbnails of each image in the select form. Django's filter_horizontal is very close to what I am looking for, but it can't display thumbnails of the images Anyway, the models involved look something like this: class Image(models.Model): original = models.ImageField(upload_to='images') medium = ... thumbnail = ... class Project(models.Model): title = models.CharField(max_length=100) images = models.ManyToManyField(Image, blank=True) description = RichTextField(max_length=1000) content = RichTextField() This is a mockup of what I am trying to achieve. I've been reading through the documentation on Forms, ModelForms, and Widgets, but I am not entirely sure how to piece it all together or if I'm looking at the wrong thing entirely. Any help would be much appreciated, even if it's just pointing me in the right direction. -
Customize the nested data in Serializer
I have a ModelSerializer: class WorkOrderRetrieveSerializer(ModelSerializer): workordercomments = WorkOrderCommentForWorkOrderSerializer(many=True, read_only=True) class Meta: model = WorkOrder fields = "__all__" The JSON data is bellow: { "id": 1, "workordercomments": [ ..... { "id": 21, "content": "test files", "files": "[71]", "ctime": "2018-01-11T11:03:17.874268+08:00", "uptime": "2018-01-11T11:03:17.874362+08:00", "workorder": 1, "comment_user": { "id": 5, "username": "test03", "is_admin": true } } ], "workorder_num": "WON15118747168252", "name": "order01", "content": "first conntetn", "workordertype": "teck", "workorder_status": "created", "user_most_use_email": "lxas@128.com", "server_id": null, "public_ip": null, "belong_area": null, "files": null, "ctime": "2017-11-28T21:11:56.826971+08:00", "uptime": "2017-11-28T21:11:56.827064+08:00", "to_group": 3, "user": 2 } The "files": "[71]", in my JSON is a string of a group contains file ids. workordercomments is the related-name of the workorder. I want in the JSON workordercomments shows the files like this: { "id": 21, "content": "test files", "files": "['/media/images/xxxxx.png']", "ctime": "2018-01-11T11:03:17.874268+08:00", "uptime": "2018-01-11T11:03:17.874362+08:00", "workorder": 1, "comment_user": { "id": 5, "username": "test03", "is_admin": true } } The "files" value I want to is the link rather than its id. "files": "['/media/images/xxxxx.png']", or "files": ['/media/images/xxxxx.png'], Is it possible to customize the format? should I come true what function in serializer ? -
Pass data from Views.py to Forms.py
I am trying to move data from my views.py to my forms.py pages. I am using the FormWizard, however i dont think it will matter here. views.py def get_context_data(self, form, **kwargs): context = super(CheckoutWizard, self).get_context_data(form=form, **kwargs) kwargs = super(CheckoutWizard, self).get_form_kwargs() def get_form_kwargs(self): kwargs = super(CheckoutWizard, self).get_form_kwargs() kwargs.update({'first_name': 'james'}) kwargs.update({'last_name': 'bond'}) form = CreditCardForm(kwargs) return kwargs forms.py - in CreditCardForm def __init__(self, *args, **kwargs): for a in args: for key in a: print("key: %s , value: %s" % (key, a[key])) super(CreditCardForm, self).__init__(*args, **kwargs) In the forms file above I am accessing the data in *args with the nested loops because if i call args without the * i get this back ({'first_name': 'james', 'last_name': 'james'},) which i believe is a tuple with a dictionary in it. I have seen other solutions where other people are using **kwargs instead. My current solution feels a bit hacky so if there is a more correct or simpler way of doing this id appreciate the help. Its also strange to me that in views i am adding to kwargs, but then accessing that data in args. Any explanation on the differences would also be appreciated. Thanks! -
Django - adding checkout to django-carton
I've built a product app that utilizes django-carton, and I want to add 'checkout' functionality. I know the best route would be to use something like django-oscar, but in the spirit of finishing what I've started, and learning along the way I want to see if I can add checkout to this app. I'm looking for a starting point - since the checkout app will need to hand off for payment, and in some cases, deliver a link to a product. What is the best way forward for that? -

(1129, "Host 'IP is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'")
Please do not mark as duplicate if possible. I do find out LOTS asking about this problem and all the results seem to be either flush hosts; or change the max_connect_errors variable to a higher value. But none of the posts are able to really have a reason of this. I am wondering are those the only two options? For me, this happened not right after but few days after I used galera to create few master to master mariadb replications. I had no idea why this is happening and it just happened randomly, even though I did try the flush hosts which worked perfectly each time, but it was still weird how this even happened. Does replication have something to do with this though? I did read some posts about crontab by the time when this error started to happen, I was researching how to make a bash to check maria db connection, cluster status and cluster size but haven't even done it yet. Today, I figured there is one way that this error will happen for sure, which is by going to django admin dashboard and go to one of my models. The first page only displays 100 … -

Django templates inheritance looses original data
I'm learning django. I have a site with a data table that has the following html template: {% load static %} {% load table_tags %} <link href="{% static 'table/css/bootstrap.min.css' %}" rel="stylesheet"> <script src="{% static 'table/js/jquery.min.js' %}"></script> <script src="{% static 'table/js/bootstrap.min.js' %}"></script> <link href="{% static 'table/css/datatable.bootstrap.css' %}" rel="stylesheet"> <script src="{% static 'table/js/jquery.browser.min.js' %}"></script> <script src="{% static 'table/js/jquery.dataTables.min.js' %}"></script> <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>Impala query metrics</title> </head> <body> <div class="container" style="margin: 10px 10px 10px"> <h1>Impala Query metrics</h1> <br /> {% render_table people %} </div> <a href="/logout">logout</a> {% block content %} {% endblock %} </body> When i try to inherit with another template by adding {% extends "base.html" %} to the first line, it inherits with base.html but my original data table disappears.

Differences in import expressions?
I have a question regarding the import//from statement in python. In my views.py file (Project/App/views.py) I have this line: from django.views.generic import TemplateView, ListView Why do I have to include 'django' in that line? Why is it not enough to specify which directory (views) that the generic file is located in? This is what I have done in many of my previous python-only scripts - an example being: from random import foo as well as in my current django url.py file. There, I have: from app.views import view Why don't I have to specify that further, like with the first example where 'django' is included in the path-specification? How come I don't have to write it like this: from project.app.views import view Thank you! -

How can I move data from views.py to a models.py in python/django in this case?
I put these files in the order the data travels. First the user submits a ticker via Charfield on the add file. Then the add function creates an instance of the score class by submitting the ticker value, which works. I also calculate points in add, but I can't figure out a way to send points to the class in models also. All of the examples I've seen on StackOverflow usually have variables in the class being related to some CharField or ForeignKey. So it possible to send points to score()? I also know scoreCalculate works. The error this code generates: File "~/models.py", line 6, in score points; NameError: name 'points' is not defined Of course it isn't defined, I'm just not sure what to define it as. add.html <form action="{% url 'add' %}" method="post"> {% csrf_token %} <label for="ticker">Ticker</label><br /> <input type="text" name="ticker" id="ticker"/> <br><br> <input type="submit" value="submit" /> </form> views.py from django.shortcuts import render, redirect from django.http import HttpResponse from .models import score from Rssfeed import scoreCalculate def add(request): if(request.method == 'POST'): ticker = request.POST['ticker'] pts = scoreCalculate(ticker=ticker) sc = score(ticker = ticker) sc.save() return redirect('/') else: return render(request, 'add.html') models.py from django.db import models from datetime import … -

How to make a double Inner Join in django?
I have a django aplication that have to show the country name and the city name of a "need" in the list of candidate. To explain this better I have the next picture: So, here is the process: First, someone posts a "need" with their respective country and city. The city and the country are in diferent model. Then, the candidate can make an offer to resolve that need. I want to see in a list, all the offers I send to the need (just 1 offer to 1 need) but in my html template I want to display the name of the country and the city of the need.

Django widget tweaks popover won't move with content
I'm using django widget tweaks to render a form field that is required. It all works fine, if the field is blank, I see a cute little popover that says field is required and all that, but if I scroll the page (the form is a little big), the popover won't move with the form field. It'll stay put and that is not good. Here's my code: {% load widget_tweaks %} {{form.order_number.label}} {% render_field form.order_number required="true" %} Also, this is happening only on Firefox, not on Chrome. I'm on Firefox 57.0. Here's a screenshot to help. In Pic1, you'll see it is supposed to be where I like it without scrolling. In Pic2, it has gone way upwards to the top of the div when I scroll up. Could someone please explain why this is happening and how I can fix it?
