FormFor

The form.FormFor type can be used to generate HTML forms for a specified model.

So given this Talk model:

type Talk struct {
	ID            int          `json:"id" db:"id"`
	CreatedAt     time.Time    `json:"created_at" db:"created_at"`
	UpdatedAt     time.Time    `json:"updated_at" db:"updated_at"`
	UserID        int          `json:"user_id" db:"user_id"`
	Title         string       `json:"title" db:"title"`
	Description   nulls.String `json:"description" db:"description"`
	Notes         nulls.String `json:"notes" db:"notes"`
	ParentID      nulls.Int    `json:"parent_id" db:"parent_id"`
	Abstract      string       `json:"abstract" db:"abstract"`
	AudienceLevel string       `json:"audience_level" db:"audience_level"`
	IsPublic      nulls.Bool   `json:"is_public" db:"is_public"`
	TalkFormatID  int          `json:"talk_format_id" db:"talk_format_id"`
}

and this template:

<%= form_for( talk, {action:"/talks", method: "PUT"}) { %>

<div class="row">
  <div class="col-md-12">
    <%= f.InputTag("Title") %>
  </div>
  <div class="col-md-6">
    <%= f.TextArea("Abstract", {hide_label: true}) %>
  </div>


  <div class="col-md-6">
    <%= f.SelectTag("TalkFormatID", {options: talk_formats}) %>
    <%= f.SelectTag("AudienceLevel", , {options: audience_levels}) %>
  </div>

  <div class="col-md-12">
    <%= f.TextArea("Description", {rows: 10}) %>
  </div>

  <div class="col-md-12">
    <%= f.TextArea("Notes", {rows: 10}) %>
  </div>
</div>
<% } %>

you will get output similar to this:

<form action="/talks" id="talk-form" method="POST">
  <input name="authenticity_token" type="hidden" value="cd998be98a99b452481c43fd3e4715e4e85333a45b982ac999">
