As a user, I can upload keywords

[rosle]

What happened

✅ Change the default pages controller to dashboard controller
✅ Add an upload form on the user dashboard
✅ Parse the uploaded csv

Insight

Implement the upload form which ties to the KeywordFile schema which validate for the file type

Use the CSV Library to parse the file

Proof Of Work

• Display the upload form on the user dashboard

  

• When the user uploads the invalid file type, displays the error

  

• When the user uploads the valid csv, parses and displays the parsed content

  For example we upload the file with this content

  hotel
  animal
  cats
  restaurants

It's a great idea to use embedded_schema. I just read about it last weekend. It's the closest to implement some kind of form object 💪

This will return nil as it's not using get!

How about:

defp validate_file_ext(changeset) do
  if Enum.member?(@accept_file_ext, Path.extname(file.filename)) do
    changeset
  else
	add_error(changeset, : file, "is not supported")
  end
end

The return of an empty array [] is kind of strange while returning changeset seems more expected.

I rechecked this one. I found something interesting 📝

When using the validate_change, seems like it will only validate when the value is not nil - https://hexdocs.pm/ecto/Ecto.Changeset.html#validate_change/3. So after removing it out, there is one case that if the file is nil, it will still validate and the error occurs when file.filename because the file is nil. For this, we might need to add more condition/clause function to handle this case 👍
