I am confused about the Schema setup,

I am setting up a new application and I want to seed files in it as well. I tried to mix to create the schema mix phx.gen.html Delish.food delish_foods title:string ingredients:string summary:string date:integer
I keep getting this error even if I try phx.gen.schema, the error looks like this

** (Mix) Expected the context, "Delish.food", to be a valid module name

mix phx.gen.html, phx.gen.json, phx.gen.live, and phx.gen.context
expect a context module name, followed by singular and plural names
of the generated resource, ending with any number of attributes.
For example:

    mix phx.gen.html Accounts User users name:string
    mix phx.gen.json Accounts User users name:string
    mix phx.gen.live Accounts User users name:string
    mix phx.gen.context Accounts User users name:string

The context serves as the API boundary for the given resource.
Multiple resources may belong to a context and a resource may be
split over distinct contexts (such as Accounts.User and Payments.User).

Do I just set up the schema with one title:string?

mix phx.gen.html - a command that will generate Context module and Schema
https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.Html.html

while
mix phx.gen.schema - will generate Schema
https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.Schema.html

P.S. Sorry, posted too early. You already mentioned using mix pxh.gen.schema
P.P.S I think it’s supposed to be mix phx.gen.schema Delish.Food - ‘food’ should be started with a capital latter to indicate a module.

I am still getting the same error

** (Mix) Expected the schema, "delish_foods", to be a valid module name

mix phx.gen.html, phx.gen.json, phx.gen.live, and phx.gen.context
expect a context module name, followed by singular and plural names
of the generated resource, ending with any number of attributes.
For example:

    mix phx.gen.html Accounts User users name:string
    mix phx.gen.json Accounts User users name:string
    mix phx.gen.live Accounts User users name:string
    mix phx.gen.context Accounts User users name:string

The context serves as the API boundary for the given resource.
Multiple resources may belong to a context and a resource may be
split over distinct contexts (such as Accounts.User and Payments.User).

Could you give me an example using this mix phx.gen.html Delish.food delish_foods title:string ingredients:string summary:string date:integer? on how the two mix commands are different?

I see. I got a bit confused and thought you wanted to only create Schema, but you’re trying to create Context and Schema.

mix phx.gen.html Foods Food delish_foods title:string ingredients:string summary:string date:integer

Foods - Context Module
Food - Schemade module
delish_foods - table name

It will create:

  • a context module in lib/app/foods.ex for the accounts API
  • lib/app/foods - folder
  • lib/app/foods/food.ex - schema module

It will also create templates, views, and a controller. It will show all the files it created in the terminal.

You forgot about the Context Module.

mix phx.gen.html <Context module> <Schema Module> <plural table name> <list of attributes>

What is Context Module is the main defmodule? the Schema Module is the blueprint for the data
