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

问题描述

我想使用的 acts_as_taggable_on 。注：我是新来的回报率

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!

这是很容易做到，如果仅仅使用标准文本输入字段，但我想用在一种类型（固定的行业类别标签是predefined）方框中打勾，然后允许用户添加逗号在输入字段分隔标签。

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.

我已经用各种方式这个问题发挥各地，......一个接<一个启发href=\"http://stackoverflow.com/questions/2082399/thinking-sphinx-and-acts-as-taggable-on-plugin\">this问题 ......但我不能让它开始工作。

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

下面是我到目前为止有：

Here is what I have so far:

# 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（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"

在我公司的控制器我有

And in my Company controller I have

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

但是，这将导致验证错误：

But this causes a validation error:

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

谁能暗示我怎么能做到这一点吗？

Can anyone hint at how I can do this right?

一个相关的问题是，如果这是做它在所有的好办法？我会过得更好只使用一个分类模型通过合资模式分配部门的标签？

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，我解决我的问题。它被证明是相当简单。唉，我结束了创建通过联合sectorizations表中单独的领域模型。但是，如果有人有兴趣，我只是想对我做了什么的情况下上述...

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...

在我的公司模式

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

在表单

# 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"

和在公司的控制器（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
