Nested content tags in rails 5 view helpers
# because i can never remember exactly how and when to use concat
# when building content in helpers
def nested_content
content_tag 'div' do
concat(content_tag 'span', 'span block')
concat(tag 'br')
concat(link_to 'root link', root_path)
concat(tag 'br')
concat(link_to('#') do
concat(content_tag 'h2', 'Head \'em off')
concat(tag 'br')
content_tag 'div', (content_tag 'span',(concat 'dudue'))
end)
end
end
Another Example for Bootstrap 4 with specifying mandatory field etc.
def form_field_tag(type, label, attr, column, opts={})
content_tag(:div, class: 'form-group row') do
concat(
label_tag("#{attr}[#{column}]", class: 'col-lg-3 col-form-label form-control-label') do
concat label
concat content_tag(:span, ' *', class: 'text-danger') if opts[:required]
end
)
concat(
content_tag(:div, class: 'col-lg-9') do
case type
when 'text_field'
concat text_field_tag("#{attr}[#{column}]", nil,
class: 'form-control', 'aria-describedby' => opts[:hint_id],
required: opts[:required])
when 'text_area'
concat text_area_tag("#{attr}[#{column}]", nil,
class: 'form-control', 'aria-describedby' => opts[:hint_id],
required: opts[:required])
when 'select'
concat select_tag("#{attr}[#{column}]", options_for_select(opts[:select_options], opts[:selected_option]),
class: 'form-control', 'aria-describedby' => opts[:hint_id],
required: opts[:required])
end
concat content_tag(:small, opts[:hint], id: opts[:hint_id],
class: 'form-text text-muted')
end
)
end
end
= form_field_tag('text_field', 'Source', 'article', 'source', hint: "Ex: journel", hint_id: 'media_SourceHelp', required: true)
