How does a multi-tenant application fit in Microservices based architecture?
I have a SaaS based multi-tenant monolith application (built with Django), that I want to divide into microservices based architecture. But I am not sure how to divide the application into correct partitions. And on what aspects should I take care of? In case of monolith application, it's easy to understand that I have a tenant model that decides the schemas but how this will be done in microservices if I want each service to be multi-tenant? Or should I even make the services multi-tenant? -
Unable to rebuild elasticsearch indexes when running in docker-compose
I am playing with a Django project and elasticsearch 6.3.1 (using django-elasticsearch-dsl). When I am running the project from my own environment having the elasticsearch running in a docker, then everything works fine. The command I am using to run the elasticsearch in docker is docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.3.1 When I am attempting to run the django project with the elasticsearch together in docker using docker-compose then I get the following error when running python manage.py search_index --rebuild from inside the container of the django project. elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters: [prettyUrl : {type=text}] [summary : {analyzer=html_strip, fields={raw={type=keyword}}, type=text}] [score : {type=float}] [year : {type=float}] [genres : {analyzer=html_strip, fields={raw={type=keyword}, suggest={type=completion}}, type=text}] [id : {type=integer}] [title : {analyzer=html_strip, fields={raw={type=keyword}, suggest={type=completion}}, type=text}] [people : {analyzer=html_strip, fields={raw={type=keyword}, suggest={type=completion}}, type=text}]') Now if i try to add an object then the error coming up is RequestError(400, 'action_request_validation_exception', 'Validation Failed: 1: type is missing;') NOTE that i do not have any of these problems when I am running the django project from the terminal and the elasticsearch using docker run with the command above.

Aggregate the results of a union query without using raw
I have a table that looks like this date car_crashes city 01.01 1 Washington 01.02 4 Washington 01.03 0 Washington 01.04 2 Washington 01.05 0 Washington 01.06 3 Washington 01.07 4 Washington 01.08 1 Washington 01.01 0 Detroit 01.02 2 Detroit 01.03 4 Detroit 01.04 2 Detroit 01.05 0 Detroit 01.06 3 Detroit 01.07 1 Detroit I want to know how many car crashes for each day happened in the entire nation, and I can do that with this: Model.values("date") \ .annotate(car_crashes=Sum('car_crashes')) \ .values("date", "car_crashes") Now, let's suppose I have an array like this: weights = [ { "city": "Washington", "weight": 1, }, { "city": "Detroit", "weight": 2, } ] This means that Detroit's car crashes should be multiplied by 2 before being aggregated with Washington's. It can be done like this: from django.db.models import IntegerField when_list = [When(city=w['city'], then=w['weight']) for w in weights] case_params = {'default': 1, 'output_field': IntegerField()} Model.objects.values('date') \ .annotate( weighted_car_crashes=Sum( F('car_crashes') * Case(*when_list, **case_params) )) However, this generates very slow SQL code, especially as more properties and a larger array are introduced. Another solution which is way faster but still sub-optimal is using pandas: aggregated = false for weight in weights: ag = Model.values("date") \ .annotate(car_crashes=Sum('car_crashes')) … -
Getting Django error (models.E028). for 6 different models after moving from the Desktop folder to the var/www folder on Ububtu Server
I recently moved my django project files from a laptop to a web server. After moving the files I ran the django dev server to test things and everything was fine. After moving the project files once to the var/www folder I attempted again to see if everything still worked before finishing the process of launching the project. I am now getting a django error (models.E028) and don't know how to solve it. I have looked through the models.py folder where these models are and everything appears the same as before. Also I have yet to destroy the copies of the project on the laptop so I tried to launch it there and it works with no errors. Unfortunately the Django docs don't give further explanation of the error, or where to start looking for the cause. I'm sure the error has to do with moving the files from one location to another on the server, but I can't think of why it would affect the models. They have to be in the folder they are located in now, so moving them back isn't a solution. I moved the folder with the following command: sudo mv file/I/needed/to/move /var/www/ Here is … -
Django JSONField - get source text
When using a JSONField, the contents are automatically decoded from JSON into python objects when reading the value. I have a use-case where I'm encoding the string back into JSON to embed in a template. Is there any way to just get the raw JSON string from the object? -
Django - Create unique ID for multiple columns
I am creating a model in Django and want to create a unique ID that is "grouped" on multiple columns.

Django. 301 Redirect from old URL to new
Hello! Please tell me how to organize a redirect correctly. There is an old version of the site and a new one. In the old version (another CMS, not Django) the objects have their own URL, in the new revised scheme, and the objects have a different URL. In each object on the new site, there is a completed field with the old URL. In model.py it looks like this: old_url = models.CharField('Old URL', blank=True, max_length=100) I specifically moved the old url to a separate field. Or was it not necessary to do this? Question. How to set up a redirect correctly, so that after going to the object using the old URL, the site visitor will be redirected to the new URL of this object? -
Auto increment field in context of foreign key
I am writing as an (personal) exercise a little Issue tracker in django. I want to have for a model an integer field that is unique (auto incremented), but not for the whole model/table but in the context of a related model. class Parent(models.Model): name = models.CharField(max_length=10) class Child(models.Model): parent = models.ForeignKey(Parent, models.CASCADE) identifier = models.IntegerField() The goal is to have a parent classes with the names "ABC" and "XYZ". Now i want to create multiple instances of child classes and the identifiers should more or less auto increment in the context of the Parent class. Instance #1: parent is "ABC" -> identifier = 1 Instance #2: parent is "ABC" -> identifier = 2 Instance #3: parent is "DEF" -> identifier = 1 How do i achieve this in a transaction safe manner? -

Translating a PHP project to Django framework
I'm a PHP developer and I'm very new to Django. I am stuck and don't know where else to turn to. I am trying to translate a program I developed in PHP into Django. So many aspects are working well, but I'm stick particular where I'm trying to display quizzes from a database. There is a database table called "table_assessment". It contains accessmemts. There is another table called "table_scores". Assessments are only sent to the database of the score is => 80%. That's the same exact thing I'm trying to implement in Django. My primary area of interest is the aspect where I get questions, options and answers all from one table, and update another table if the user scores =>80% Please help me out. My PHP code looks like this: <form id="form_assessment" rol="form" method="post" action='<?php echo $_SERVER["PHP_SELF"]."?assessment_id=".$assessment_id; ?>'> <?php $ql=mysqli_query($conn, "SELECT * from table_assessment where course_id ='".$assessment_id."'"); $count=0; while($row=mysqli_fetch_array($ql,MYSQLI_ASSOC)){ $count++; echo "<p>".$row["assessment_content"]."</p>"; echo "<ul style='list-style-type:none; required'>"; echo '<li><input type="radio" name="r_'.$count.'" value="a"/> '.$row["option_a"].'</li>'; echo '<li><input type="radio" name="r_'.$count.'" value="b"/> '.$row["option_b"].'</li>'; echo '<li><input type="radio" name="r_'.$count.'" value="c"/> '.$row["option_c"].'</li>'; echo '<li><input type="radio" name="r_'.$count.'" value="d"/> '.$row["option_d"].'</li>'; echo "</ul>"; } ?> <div> <input type="submit" id="btn_assessment" name="btn_assessment" class="btn btn-success" value="FINISH"> </div> </form> This checks to see if … -
Graphene Django mutation returning object with subobjects fails
When I execute a mutation (with SerializerMutation) and return the created object, the response contains an AssertionError that states User Error: expected iterable, but did not find one for field CreateTableMutationPayload.footSet The issue is in executor.py complete_list_value that checks that the footSet is an iterable. It is in fact a RelatedManager, which is not iterable as is. Normally, you'd just do a table.foot_set.all() to get the iterable. I find it stange that it is working fine in Queries but not Mutations. I created a sample project to illustrate this. I have a pretty simple model of Table with several Foot. Both objects are exposed with Relay and this works great. Querying: { tables { edges { node { id, name, height footSet { edges { node { id, number, style } } } } } } } } returns: { "data": { "tables": { "edges": [ { "node": { "id": "VGFibGVOb2RlOjE=", "name": "test1", "height": 11, "footSet": { "edges": [ { "node": { "id": "Rm9vdE5vZGU6MQ==", "number": 1, "style": "plain" } }, { "node": { "id": "Rm9vdE5vZGU6Mg==", "number": 2, "style": "Almost plain" } } ] } } } ] } } } But a mutation: mutation { createTable(input: { name:"test3" height: 60 … -

Using UUIDField in Django keeps creating new migrations
I have a simple model:: class HasUUID(models.Model): name = models.CharField(max_length=10) batchid = models.UUIDField(default=uuid.uuid4(), unique=True) running makemigrations gives me the migration:: operations = [ migrations.CreateModel( name='HasUUID', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('name', models.CharField(max_length=10)), ('batchid', models.UUIDField(default=uuid.UUID('79a2d9fe-e1d0-4d4b-884f-fad0bfb14f0f'), unique=True)), ], ), ] Running migrate gives me the new table no problem. But I can run makemigrations again and I get:: operations = [ migrations.AlterField( model_name='hasuuid', name='batchid', field=models.UUIDField(default=uuid.UUID('3b96231c-5848-430b-aa90-b6e41b11fd0a'), unique=True), ), ] and while I have lived with this for a while, manually removing the unnecessary code, I need to resolve it. so I think, make the default a separate function in the migrations as shown in various examples:: def create_uuid(apps, schema_editor): m = apps.get_model('web', 'HasUUID') for inst in m.objects.all(): inst.batchid = uuid.uuid4() inst.save() ... migrations.CreateModel( name='HasUUID', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('name', models.CharField(max_length=10)), ('batchid', models.UUIDField(blank=True, null=True)), ], ), migrations.RunPython(create_uuid), migrations.AlterField( model_name='hasuuid2', name='batchid', field=models.UUIDField(default=uuid.uuid4, unique=True) ), same problem. So I tried making the default a separate function in the model:: def create_uuid(): return uuid.uuid4() class HasUUID2(models.Model): name = models.CharField(max_length=10) batchid = models.UUIDField(default=create_uuid(), unique=True) and this gets me this migration:: migrations.CreateModel( name='HasUUID3', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('name', models.CharField(max_length=10)), ('batchid', models.UUIDField(default=uuid.UUID('335c3651-b04e-4ed8-a91d-f2da3f53dd8f'), unique=True)), ], ), and again, keeps generating new migrations.
