elixirChatter : basic project on elixir

to create a new pheonix server :

mix phx.new <project_name>

the chatter folder has been created. follow the readme of that folder and come back here.

psql guide - https://chartio.com/resources/tutorials/how-to-list-databases-and-tables-in-postgresql-using-psql/

mix ecto.gen.migration add_table : to add new table write in the new migration file

and run : mix ecto.migrate

create model for the database table:

define schema and changeset in new folder in lib. (here it is in schemas->chatter_box.ex)

so far there is nothing in the table we have just defined the schema.

we can query the database by using ecto. : lib->chatter_queries.ex (but as there is nothing till now, nothing to query)

to put the rows in the tables in database.

seed.exs need to send data. it will send data by repo.insert query which is in chatter_queries.ex->create_chat. create_chat validates the input with the changeset.

to run seeds.exs : mix run priv/repo/seeds.exs

to fetch data

1. create a route in router (/get/:status)

2. create a controller and add the functions u will be calling too (chatter_controller/get)

3. use render function that has a template (here, getting_message.html)

4. for that template , we need to create template folder chatter(based on controller name) and make a file getting_message.html.eex ( elixir strictly follows name convention)

5. create a chatter_view.ex (follow the naming convention)
