-- | Forms usually begin with a 'formFor' expression.
--
-- This is how a simple form can look like:
--
-- > renderForm :: Post -> Html
-- > renderForm post = formFor post [hsx|
-- >     {textField #title}
-- >     {textareaField #body}
-- >     {submitButton}
-- > |]
--
-- Calling this form from inside your HSX code will lead to the following HTML being generated:
--
-- > <form method="POST" action="/CreatePost" id="" class="new-form">
-- >     <div class="form-group" id="form-group-post_title">
-- >         <label for="post_title">Title</label>
-- >         <input type="text" name="title" id="post_title" class="form-control" />
-- >     </div>
-- >
-- >     <div class="form-group" id="form-group-post_body">
-- >         <label for="post_body">Body</label>
-- >         <textarea name="body" id="post_body" class="form-control"></textarea>
-- >     </div>
-- >
-- >     <button class="btn btn-primary">Create Post</button>
-- > </form>
--
-- You can see that the form is submitted via @POST@. The form action has also been set by default to @/CreatePost@.
--
-- All inputs have auto-generated class names and ids for styling. Also, all @name@ attributes are set as expected.
--
-- __Field Values:__
--
-- A form control is always filled with the value of the given field when rendering. For example, given a post
--
-- > let post = Post { ..., title = "Hello World" }
--
-- Rendering this, the input value will be set like:
--
-- >>> {textField #title}
-- <input ... value="Hello World" />
--
-- __Validation:__
--
-- When rendering a record that has failed validation, the validation error message will be rendered automatically.
--
-- Given a post like this:
--
-- > let post = Post { ..., title = "" }
-- >     |> validateField #title nonEmpty
--
-- Rendering @{textField #title}@, the input will have the css class @is-invalid@ and an element with the error message will be rendered below the input:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label for="post_title">Title</label>
-- >     <input
-- >         type="text"
-- >         name="title"
-- >         placeholder=""
-- >         id="post_title"
-- >         class="form-control is-invalid "
-- >     />
-- >     <div class="invalid-feedback">This field cannot be empty</div>
-- > </div>

-- | Allows a custom form action (form submission url) to be set
--
-- The URL where the form is going to be submitted to is specified in HTML using the form's @action@ attribute. When using 'formFor' the @action@ attribute is automatically set to the expected path.
--
-- E.g. given the below 'formFor' code, the @action@ is set to @/CreatePost@ or @/UpdatePost@:
--
-- > renderForm :: Post -> Html
-- > renderForm post = formFor post [hsx|
-- >     {textField #title}
-- >     {textareaField #body}
-- >     {submitButton}

--
-- To override the auto-generated @action@ attribute use the 'formFor\'' function:
--
-- > renderForm :: Post -> Html
-- > renderForm post = formFor' post "/my-custom-endpoint" [hsx||]
--
-- If you pass an action to that, you need to wrap it with 'pathTo':
--
-- > renderForm :: Post -> Html
-- > renderForm post = formFor' post (pathTo CreateDraftAction) [hsx||]

--
-- __Example:__
--
-- > renderForm :: Post -> Html
-- > renderForm post = formFor post [hsx|
-- >     {textField #title}

--
-- This will generate code like this:

--
-- __Help Texts:__
--
-- You can add a help text below a form control like this:
--
-- > {(textField #title) { helpText = "Max. 140 characters"} }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">

-- >
-- >     <input type="text" name="title" id="post_title" class="form-control" />
-- >     <small class="form-text text-muted">Max. 140 characters</small>
-- > </div>
--
--
-- __Custom Field Label Text:__
--
-- By default, the field name will be used as a label text. The camel case field name will be made more human-readable of course, so @contactName@ will turn to @Contact Name@, etc. Sometimes you want to change this auto-generated input label to something custom. Use @fieldLabel@ for that, like this:
--
-- > {(textField #title) { fieldLabel = "Post Title"} }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label for="post_title">Post Title</label>
-- >     <input type="text" name="title" id="post_title" class="form-control" />
-- > </div>
--
--
-- __Custom CSS Classes:__
--
-- You can add custom CSS classes to the input and label for better styling. Set @fieldClass@ for adding a class to the input element and @labelClass@ for the label element:
--
-- > {(textField #title) { fieldClass="title-input", labelClass = "title-label" } }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label class="title-label" for="post_title">Title</label>
-- >     <input
-- >         type="text"
-- >         name="title"
-- >         id="post_title"
-- >         class="form-control title-input"
-- >     />
-- > </div>
--
-- Of course, the CSS classes for validation are still set as expected.
--
-- __Placeholder:__
--
-- > {(textField #title) { placeholder = "Enter your title ..." } }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label for="post_title">Title</label>
-- >
-- >     <input
-- >         type="text"
-- >         name="title"
-- >         id="post_title"
-- >         placeholder="Enter your title ..."
-- >         class="form-control"
-- >     />
-- > </div>
--
--
-- __Required Fields:__
--
-- You can mark an input as required like this:
--
-- > {(textField #title) { required = True } }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label for="post_title">Title</label>
-- >
-- >     <input
-- >         type="text"
-- >         name="title"
-- >         id="post_title"
-- >         required="required"
-- >         class="form-control"
-- >     />
-- > </div>
--
-- __Autofocus:__
--
-- You can mark an input with autofocus, to ensure it will be given the input focus on page load, like this:
--
-- > {(textField #title) { autofocus = True } }
--
-- This will generate code like this:
--
-- > <div class="form-group" id="form-group-post_title">
-- >     <label for="post_title">Title</label>
-- >
-- >     <input
-- >         type="text"
-- >         name="title"
-- >         id="post_title"
-- >         autofocus="autofocus"
-- >         class="form-control"
-- >     />

-- | Select inputs require you to pass a list of possible values to select.
--
-- > formFor project [hsx|
-- >     {selectField #userId users}
-- > |]
--
-- In the example above the variable users contains all the possible option values for the select.
--
-- You also need to define a instance @CanSelect User@:
--
-- > instance CanSelect User where
-- >     -- Here we specify that the <option> value should contain a `Id User`
-- >     type SelectValue User = Id User
-- >     -- Here we specify how to transform the model into <option>-value
-- >     selectValue = get #id
-- >     -- And here we specify the <option>-text
-- >     selectLabel = get #name
--
-- Given the above example, the rendered form will look like this:
--
-- > <!-- Assuming: users = [User { id = 1, name = "Marc" }, User { id = 2, name = "Andreas" }] -->
-- > <form ...>
-- >     <select name="user_id">
-- >         <option value="1">Marc</option>
-- >         <option value="2">Andreas</option>
-- >     </select>
-- > </form>
--
-- If you want a certain value to be preselected, set the value in the controller. For example, to have the first user be preselected in the above example:
--
-- > action NewProjectAction = do
-- >     users <- query @User |> fetch
-- >     let userId = headMay users |> maybe def (get #id)
-- >     let target = newRecord @Project |> set #userId userId
-- >     render NewView { .. }
