Django - DROP and CREATE DB - No changes detected
I'm moving my project from Sqlite3 to MySQL database. I've connected new MySQL database to Django and run manage.py migrate. There were some errors but tables were created so I decided to DROP the database and recreate it. The problem is that even when I DROP the database DROP DATABASE mydb; And then create it CREATE DATABASE mydb; And deleted migrations Django's manage.py makemigrations says no changes detected which is very weird since it should track changes inside recreated database which is empty. Do you know what to do and why it behaves this way? mysql> DROP DATABASE keywords_search; Query OK, 13 rows affected (0,19 sec) mysql> SHOW DATABASES; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0,00 sec) mysql> CREATE DATABASE keywords_search; Query OK, 1 row affected (0,00 sec) mysql> use keywords_search; Database changed mysql> show tables; Empty set (0,00 sec) mysql> -
DRF: creating new object in a model with 'ManyToMany' field and 'through' table
I have the following Django models: class Product(models.Model): name = models.CharField(max_length=250, unique=True) quantity = models.IntegerField(default=0) class Order(models.Model): products = models.ManyToManyField( Product, through='PositionInOrder' ) discount = models.CharField(max_length=50, blank=True) total_sum = models.DecimalField(max_digits=11, decimal_places=2, default=0) class PositionInOrder(models.Model): sale = models.ForeignKey(Order) product = models.ForeignKey(Product) quantity = models.PositiveIntegerField() price = models.PositiveIntegerField() And the following serializers: class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = '__all__' class PositionInOrderSerializer(serializers.HyperlinkedModelSerializer): sale = serializers.ReadOnlyField() product = serializers.ReadOnlyField() class Meta: model = PositionInOrder fields = "__all__" class OrderSerializer(serializers.ModelSerializer): products = PositionInOrderSerializer(many=True) def create(self, validated_data): products = validated_data.pop('products') order = Order.objects.create(**validated_data) return order class Meta: model = Order fields = '__all__' I want to create new Order. Send post query which contains this json: { "products": [{"id": 2606, "name": "Some name", "quantity": 140, "price": 250}], "discount": "15", "total_sum": 500 } And in the create() method of a class OrderSerialization I obtain that products=: [OrderedDict([('quantity', 140), ('price', 250)])] and there are no information about product_id and product_name. How can I get them? -
how to list files in digitalocean server with django?
I make cloud panel projects with django but i have a problem. i am click to manage button after this page show: https://s18.postimg.org/lj7qwc8p5/Ekran_G_r_nt_s_2018-02-21_19-22-33.png I make connect to paramiko.

Dynamic get_absolute_url using url query parameters
Big picture: I'd like my reverse method in get_absolute_url (see below) to return a url with a query parameter appended to it at the end, e.g. <url>?foo=bar. Further, I'd like bar to be specified by the POST request that triggered the call to get_absolute_url, either as an input to the form (but not a field represented by the model, something temporary) or as a url query parameter. I am easily able to access bar in my view using either method, but I can't seem to figure out how to access it in my model. The motivation here is that my detail page splits up the fields from my model into different tabs using javascript (think https://www.w3schools.com/howto/howto_js_tabs.asp). When the user is updating the model, they choose which tab they want to update, and then the update template only renders the fields from the model which are related to that tab. More importantly, after the user submits the update, I want the detail page to know to open the specific tab that the user just edited. (I understand how this works if the field is a part of the model; in get_absolute_url with parameters, the solution is pretty straightforward and involves using … -
Why CRUD Operations Using Ajax and Json for Django powered app is so slow ?
I am performing operations on remote legacy MySQL database having about 7000 records.Currently, it's taking around 1.5 minutes for the Update / Delete / Create operation. Should I use Rest? OR some other some other API. Any suggestions will be appreciated!

Impossible to install gettext for windows 10
I have followed all the steps shared in all stackoverflow and other questions out there to install gettext for windows (10), but still, I get the error: "Can't find msguniq, make sure you have gettext tools installed" when using internationalization in django. I have tried to download the files directly and added them to the PATH, and even an installer that had already compiled everything and added to the path automatically, but it still doesn't work, and I don't know what else to do... Help please! Thank you for your time. -
Django - validate model before saving to DB
in Django 1.10 - I want to create multiple objects by importing. Before creating them I want to validate fields to make sure as much as I can that creation will pass successfully and collect as much data as I can about invalidate fields. For example, to find out whether a char field is too long. I can use 'if' statement for each field but it's not robust. I thought of using the model Serializer. The problem is that there are models to create that uses other models that also should be created. So when trying to validate the model that depends on the other one - it fails since it's not existed yet. For example: class FirstModel(BaseModel): title = models.CharField(max_length=200) identifier = models.CharField(max_length=15) class SecondModel(BaseModel): identifier = models.CharField(max_length=15) firstModel = models.ForeignKey(FirstModel, related_name='first_model') Any idea how to validate the data? -
How to filter objects from template?
I have 2 models Category and Spending where Category is one of the Spending fields. User can create custom categories and add spending on the webpage. The question is, how to filter spendings by categories in Template? I have: {% for category in categories %} {% for spending in spendings %} 'I want this FOR have only spendings from this category.' I know how to filter objects with Object.objects.filter() but I am not sure it applies here, because categories are dynamic here -

Unknown column in field list, django slug error

ISS Webservice encoding on XML to SQL Server
I have a ISS + asp.net webservice, witch I receive a XML via post. This post calls a stored procedure on SQL Server, passing the XML as parameter. But all the accents of the XML are turned into "?", like this: <FIRST_NAME>Jos?</FIRST_NAME> Should be: <FIRST_NAME>José</FIRST_NAME> But the xml sent from a django app is correct. I've already tried utf-8 and utf-16 on the XML header, nothing changed. The procedure parameter in face is a NVARCHAR(MAX), as the webservice turns < and > in html char, so I have to do this: @DATASET NVARCHAR(MAX) SET @DATASET = REPLACE(REPLACE(@DATASET, '&lt;', '<'), '&gt;','>') DECLARE @DATASET_XML XML = @DATASET If the XML comes with the <, this would be not necessary. Where should I focus my debug? ISS maybe be doing this? Or is something on the django app or the SQL server? -
Setting up Django Channels

Django migrations, resolving merging problems
As I was changing my models.py and migrating, I got an error message saying: python manage.py makemigrations project_profile CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0033_auto_20180217_0912, 0036_auto_20180217_0927 in project_profile). To fix them run 'python manage.py makemigrations --merge' So, when I tried to follow the instructions, I got another error that one of my tables that the merged migration is now depending on do not exist anymore (I renamed it). Interestingly enough, this renaming took place during the merge operation. So, really Django should have known about it in the first place. To resolve the situation, I deleted prior migrations up to and including the migrations that was not applied, the one that caused all the headache. I tried to makemigrations and migrate again. But, Django now throws another error saying some of the models it wants to create in the database already exist. Obviously, I do not want to delete those tables and loose all that information to appease Django. So, I had to resort to some hacking solutions and actually change those tables manually and do a fake migration in order to stop Django from complaining. Having said all of that, I feel like there … -

Searching literature regarding the lack of security patching in web frameworks
I'm currently in my final year of my master in Computer Science. I'm working on a security master thesis where the goal is to automatically patch a web framework whenever a security patch is released. There is a lot of frameworks that already have this feature, however my approach is a little bit different where I'm going to detect the critical impact areas of such an update. My question is if there is anyone out there that have stumbled opun some good articles or studies of this topic? What is the practice that the industry is using when it comes to patching their systems when a new security vulnerability is exploited? I'm working with Django as my web framework, however any research on other frameworks are much appreciated! -

How to reference Users model to my app models and Provide a foreign key

Is it possible to disable a field in Django admin?
I give you my example right now because it's too hard to explain it, well, I don't know XD. I have an object named Step like this : class Step(models.Model): # Intitulé de la question title = models.CharField(max_length=300) # Appartenance belonging = models.ForeignKey('Survey', blank=True, null=True) # Renvoi à lui-même pour arborescence parent = models.ForeignKey('self', blank=True, null=True) # Ordre de la réponse order = models.PositiveIntegerField(default=0) # Complément d'information add_info = models.TextField(blank=True, verbose_name="Additional informations") def __str__(self): return (self.title) def children(self): return Step.objects.filter(parent=self, belonging=self.belonging).order_by('order', 'title') def render_step(self): template = get_template('app_questionnaire/_step.html') return template.render({'step': self}) I have one Step without parent and only one. I just wonder if it's possible to disable the EMPTY parent field in the Django admin after adding a Step ? I would like to add others Step with a parent but not another Step without a parent. I don't know if you know what I mean :) Thank you in advance !
