如何使用复选框应用带有acts_as_taggable_on 的标签? [英] How to apply tags with acts_as_taggable_on using check boxes?

问题描述

我想使用 acts_as_taggable_on.注意:我是 RoR 的新手！

I would like to assign two different "types" of tags (sector categories and free tagging) to a Company model using acts_as_taggable_on. NB: I'm new to RoR!

如果只使用标准文本输入字段，这很容易做到，但我想在一种类型(预定义的固定扇区类别标签)上使用复选框，然后允许用户添加逗号分隔的标签一个输入字段.

This is easy to do if just using standard text input fields, but I would like to use check-boxes on one type (a fixed sector category tag that is predefined), and then allow the user to add comma separated tags in an input field.

我以各种方式解决了这个问题，...一个灵感来自 这个问题...但我无法让它工作

I have played around with this problem in various ways,... one inspired by this question...but I cannot get it to work

这是我目前所拥有的:

# models/company.rb
class Company ...
  acts_as_taggable_on :tags, :sectors

  has_many :taggings,
           :as => :taggable,
           :include => :tag,
           :class_name => "ActsAsTaggableOn::Tagging",
           :conditions => { :taggable_type => "Company" }

  has_many :sector_tags, 
           :through => :taggings, 
           :source => :tag,
           :class_name => "ActsAsTaggableOn::Tag",
           :conditions => {:context => "sectors"}
end

在表单中(使用 simple_form gem)我有...

in the form (using simple_form gem) I have...

# views/companies/_form.html.haml
= simple_form_for @company do |f|
  = f.input :name
  = f.association :sector_tags, :as => :check_boxes, :hint => "Please click all that apply"
  = f.input :tag_list
  = f.button :submit, "Add company"

在我的公司控制器中，我有

And in my Company controller I have

# controllers/companies_controller.rb
def create
  @company = current_user.companies.build(params[:company])
  if @company.save
  ...
end

但这会导致验证错误:

ActiveRecord::RecordInvalid in CompaniesController#create
Validation failed: Context can't be blank

谁能暗示我如何正确地做到这一点?

Can anyone hint at how I can do this right?

一个相关的问题是，这是否是一个好方法?仅使用类别模型通过联合模型分配扇区标签会更好吗?

A related question is if this is a good way to do it at all? Would I be better off just using a Category model for assigning sector tags through a joint model?

谢谢！

推荐答案

好吧，我解决了我的问题.结果证明这很简单.唉，我最终通过联合部门化"表创建了一个单独的部门模型.但如果有人感兴趣，我只想更新我在上述案例中所做的......

Well, I solved my problem. And it turned out to be quite simple. Alas, I ended up creating a separate Sector model through a joint "sectorizations" table. But if anyone is interested, I just wanted to update on what I did in the case above...

在我的公司模型中

# models/company.rb
class Company ...
  acts_as_taggable_on :tags, :sectors
...
end

在表格中

# views/companies/_form.html.haml
= simple_form_for @company do |f|
  = f.input :name
  = f.input :sector_list, :as => :check_boxes, :collection => @sectors, :hint => "Please check all that apply"
  = f.input :tag_list
  = f.button :submit, "Add company"

并在公司控制器中(创建)

and in the company controller (create)

# controllers/company_controllers.rb
def new
  @company = Company.new
  @sectors = get_sectors
end

def get_sectors
  sectors = []
  for sector in Company.sector_counts
    sectors << sector['name']
  end
  return sectors
end
