How do you increase Characters in a text box?

1. Some possible things to consider:

• Do you have a validation that is restricting it? i.e. validate_length(:summary, max: 250)
• Are you using something like the html helper textarea/3 from the docs for your input field?
• If you share more of your code it would help people see what’s going on.

2. There are libraries like Timex which have multiple format options. There’s also strftime/3 from Elixir’s Calendar module.

I upload the code files on gitHub it is free to view

in your first bullet point you said if I am restricting anything

defmodule DishOut.Foods.Food do
  use Ecto.Schema
  import Ecto.Changeset

  schema "delish_foods" do
    field :date, :integer
    field :ingredients, :string
    field :summary, :string
    field :title, :string

    timestamps()
  end

  # alter table(:delish_foods) do 
  #   modify :content, :text
  # end
# The alter table I am increasing my char count to string over 255 for summary
  @doc false
  def changeset(food, attrs) do
    food
    |> cast(attrs, [:title, :ingredients, :summary, :date])
    |> validate_required([:title, :ingredients, :summary, :date])
  end
end

As you can see My changeset is not redistricting anything. Should I then add max: 250?

No, but You should show your form code…

String is limited to 255 char, but text is not.

It’s also strange to store date as integer, there are date and datetime types of fields.

Form Code:

<.form let={f} for={@changeset} action={@action}>
  <%= if @changeset.action do %>
    <div class="alert alert-danger">
      <p>Oops, something went wrong! Please check the errors below.</p>
    </div>
  <% end %>

  <%= label f, :title %>
  <%= text_input f, :title %>
  <%= error_tag f, :title %>

  <%= label f, :ingredients %>
  <%= text_input f, :ingredients %>
  <%= error_tag f, :ingredients %>
<div class="summary">
  <%= label f, :summary %>
  <%= text_input f, :summary %>
  <%= error_tag f, :summary %>
</div>
  <%= label f, :date %>
  <%= number_input f, :date %>
  <%= error_tag f, :date %>

  <div>
    <%= submit "Save" %>
  </div>
</.form>

Try changing text_input in your summary section to textarea (thx @kokolegorille ). Is that the behavior you’re looking for?

Also what @kokolegorille said about date and datetime field types.

textarea, withouth dash in between

This is a string field… limited to 255, use text instead.

Yes It created a bigger textarea input as per the box, but the amount of char is still the same limited to 255

In your schema update your summary to: field :summary, :text. You can see the supported mix phx.gen.schema types from docs.

Good Afternoon,

I went ahead and changed the Filed in my Schema :summary, :text. I end up getting the Error invalid unknown type

I read the documents, and :text is supported in the Schema

== Compilation error in file lib/dish_out/foods/food.ex ==

It’s :binary in the migration.
