Formulator is part of the thoughtbot Elixir family of projects.
This README follows master, which may not be the currently published version. Here are the docs for the latest published version of Formulator
Formulator is a library for Phoenix to give you:
- A label for your input, based on the attribute name
- An error label
- A class around the input if there is an error for the attribute. This allows you to easily style inputs that have errors.
You can replace the following:
<%= label form, :name %>
<%= text_input form, :name %>
<%= error_tag form, :name %>
with this:
<%= input form, :name %>
You also get the added benefit of having a class of has-error
on the input
when there is an error associated with the attribute.
By default, Formulator assumes that you want a standard text input but if you prefer, you can also specify the input type:
<%= input form, :description, as: :textarea %>
<%= input form, :count, as: :number %>
<%= input form, :email_address, as: :email %>
See Formulator.input/3 for more examples.
Add formulator to your list of dependencies in mix.exs
:
def deps do
[
{:formulator, "~> 0.3.0"},
]
end
$ mix deps.get
Formulator needs to know what module to use for the translate_error/1
function. This is commonly defined by Phoenix either in
web/views/error_helpers.ex
or web/gettext.ex
. Formulator can also
be set to not validate by default; individual input options override
the application config.
# config/config.exs
config :formulator,
translate_error_module: YourAppName.ErrorHelpers,
validate: false, # defaults to true
validate_regex: false, # defaults to true
wrapper_class: "input-set" # defaults to nil
You can import the package into all your views or individually as it makes sense:
# web/web.ex
def view do
quote do
...
import Formulator
...
end
end
To create a new release, use the bin/release
script. You must provide the
current version number and the new version number: bin/release 0.2 0.3
.
If you need hex permissions, please ask someone in the thoughtbot #elixir slack channel.
This will create a new commit with the updated fields and publish to hex.
Please be sure to follow Semver when creating a new release
