问题 I've configured docker and postgres for my Django project. When I do python manage.py runserver 0:8000 , it gives me this error: django.db.utils.OperationalError: FATAL: role "admin" does not exist However, I've been used the same configs with my previous projects and everything seems fine in those. Here is my docker-compose.yml file version: '3' services: db: image: postgres environment: - POSTGRES_DB=myproject - POSTGRES_USER=admin - POSTGRES_PASSWORD=admin_pass container_name: myproject

Laravel 5.3 Schema::create ENUM field is VARCHAR

由 |▌冷眼眸甩不掉的悲伤 提交于 2021-01-23 08:53:46
问题 I just created fresh migration. After running it I see my field type not ENUM type . It has a VARCHAR(255) type instead Schema::create('payments', function (Blueprint $table) { $table->increments('id'); $table->text('response'); $table->enum('type', ['apple', 'paypal']); $table->smallInteger('flags'); $table->timestamps(); }); Can somebody tell me what can be the reason. Am I missing something, I tried multiple times - getting same result. I'm using PostgreSQL 9.5.4 回答1: From the Laravel

Disadvantages of table with too many columns

由 旧时模样 提交于 2021-01-23 06:06:52
问题 I have some data that I need to put in a PostgreSQL database. These data are related to schools. So there are a LOT of attributes relating to the school, mostly small integers, floats or small texts. And all the data changes yearly. So I'm creating an entity called YearlyData and putting the attributes there. But the thing is, the number of attributes are around 50-60. Now these cannot be normalized because they are plain attributes of the school itself. So I ethically cannot separate them

Multiple INSERTS into one table and many to many table

由 半世苍凉 提交于 2021-01-22 10:34:06
问题 I'm trying to develop a Q&A website in PHP using a PostgreSQL database. I have an action to create a page which has a title, body, category and tags. I managed to insert all those fields however I'm having some issues inserting multiple tag values. I used this function to get the comma separated values into an array and now I want something that inserts each array element into the database (avoiding repetitions) on table tags and after that insert on my many to many relationship table

Why can't PostgreSQL do this simple FULL JOIN?

由 你。 提交于 2021-01-22 06:36:34
问题 Here's a minimal setup with 2 tables a and b each with 3 rows: CREATE TABLE a ( id SERIAL PRIMARY KEY, value TEXT ); CREATE INDEX ON a (value); CREATE TABLE b ( id SERIAL PRIMARY KEY, value TEXT ); CREATE INDEX ON b (value); INSERT INTO a (value) VALUES ('x'), ('y'), (NULL); INSERT INTO b (value) VALUES ('y'), ('z'), (NULL); Here is a LEFT JOIN that works fine as expected: SELECT * FROM a LEFT JOIN b ON a.value IS NOT DISTINCT FROM b.value; with output: id | value | id | value ----+-------+--

Deploy Django Application without Service Interruption / no Downtime

We use normal rented VMs (NO Amazon or Rackspace). How can we minimize the downtime of our application? Best would be to zero downtime. We thought about a setup with two equal application and two database servers and deploy one app/db server pair after another. The problem is keeping the data consistant. While one
