搜索多个字段 rails 5
Search multiple fields rails 5
我有以下表格：
<div class='panel' id='panel-advanced-search'>
<%= form_tag contacts_path, method: :get do %>
<div>
<div class='advanced_search'>
<div>
<%= label_tag "Contact Type" %>
<%= select_tag(:contact_type, options_for_select(Contact::TYPES, selected: params[:contact_type]), prompt: 'Any', class: 'customSelect') %>
</div>
<div>
<%= label_tag "Prospect Strength" %>
<%= select_tag(:prospect_strength, options_for_select(Contact::PROSPECT_STRENGTHS, selected: params[:prospect_strength]), prompt: 'Any', class: 'customSelect') %>
</div>
<div>
<%= label_tag "Customer" %>
<%= collection_select(:customer_account_id, :customer_account_id, Customer.order(:name), :id, :name, { prompt: '' }, class: 'customSelect select2') %>
</div>
<div>
<%= label_tag "Supplier" %>
<%= collection_select(:supplier_account_id, :supplier_account_id, Supplier.order(:name), :id, :name, { prompt: '' }, class: 'customSelect select2') %>
</div>
<div>
<%= label_tag "Company Name" %>
<%= text_field_tag :company_name %>
</div>
<div>
<%= label_tag "Name" %>
<%= text_field_tag :name %>
</div>
<div>
<%= label_tag "Job Title" %>
<%= text_field_tag :title %>
</div>
<div>
<%= label_tag "Postcode" %>
<%= text_field_tag :postcode %>
</div>
<div>
<%= label_tag :created_at, 'Created From' %>
<div class="date-picker">
<%= text_field_tag :created_at, nil, class: 'date-picker-select' %>
<span class="date-picker-btn">
<span class="icon-calendar" aria-hidden="true"></span>
</span>
</div>
</div>
<div>
<%= label_tag :updated_at, 'Created To' %>
<div class="date-picker">
<%= text_field_tag :updated_at, nil, class: 'date-picker-select' %>
<span class="date-picker-btn">
<span class="icon-calendar" aria-hidden="true"></span>
</span>
</div>
</div>
<div>
<%= label_tag "Tags" %>
<%= collection_select(:tag_list, :tag_list, @tags.order(:name), :name, :name, {}, { class: 'select2', multiple: true }) %>
</div>
<div>
<%= label_tag "Assignee" %>
<%= collection_select(:assigned_to, :assigned_to, User.all, :id, :name, { prompt: 'Any' }, class: 'customSelect select2') %>
</div>
<div>
<%= label_tag "Obsolete?" %>
<%= select_tag(:obsolete, options_for_select(['Obsolete', 'All'], selected: params[:obsolete]), prompt: 'Not obsolete?', class: 'customSelect') %>
</div>
<div>
<%= label_tag "Send Results To" %>
<%= select_tag(:subsequent_action, options_for_select([
['Report', 'report'],
['CSV Export', 'csv_export'],
['New Event', 'new_event']
]), prompt: 'None', class: 'customSelect') %>
</div>
</div>
<div class="advanced_search_btns">
<%= submit_tag submit_text %>
<%= link_to secondary_btn, contacts_path, class: 'btn-medium' %>
</div>
</div>
<% end %>
</div>
和模型中的以下方法
def self.advanced_search
Contact.where('
contact_type LIKE :search OR
prospect_strength LIKE :search OR
customer_account_id LIKE :search OR
supplier_account_id LIKE :search OR
company_name LIKE :search OR
name LIKE :search OR
title LIKE :search OR
postcode LIKE :search OR
created_at LIKE :search OR
updated_at LIKE :search OR
tag_list LIKE :search OR
assigned_to LIKE :search OR
obsolete LIKE :search
', search: "%#{search}%"
)
end
我该如何着手使用此方法，以便用户可以使用带有多个参数的搜索表单？我已经在基本搜索的索引方法中有了以下内容，所以我需要同时拥有这两种搜索形式
def index
@per_page = params[:per_page] || 20
@tags = ActsAsTaggableOn::Tag.all
if params[:search].present?
@contacts = Contact.search(params[:qs], params[:search]).order(sort_column + ' ' + sort_direction).paginate(page: params[:page], per_page: @per_page)
else
@contacts = Contact.all.order(sort_column + ' ' + sort_direction).paginate(page: params[:page], per_page: @per_page)
end
end
编辑 将上面的表格更新为完整的表格，理想情况下，我希望表格功能完全包含在模型中。

这是基本搜索：
型号
QUICK_SEARCH_FIELDS = {
name: {
column_names: 'contacts.name'
},
customers: {
joins_table: :customer,
column_names: 'contacts.name',
filters: { contact_type: 'customer' }
},
suppliers: {
joins_table: :supplier,
column_names: 'contacts.name',
filters: { contact_type: 'supplier' }
},
tags: {
tagged_with: true
}
}.with_indifferent_access
def self.search(field, query)
field = QUICK_SEARCH_FIELDS[field]
contact = all
contact = contact.joins(field[:joins_table]) if field[:joins_table]
contact = contact.where(field[:filters]) if field[:filters]
contact = contact.where("#{field[:column_names]} LIKE ?", "%#{query}%") if field[:column_names]
contact = contact.tagged_with(query) if field[:tagged_with]
contact
end
形式
<div class='panel' id='panel-search'>
<%= form_tag contacts_path, method: :get do %>
<div class='l-inline-row-block'>
<div class='l-inline-col width_120px'>
<%= select_tag(:qs, options_for_select(Contact::QUICK_SEARCH_FIELDS.keys(), selected: params[:qs]), class: 'customSelect') %>
</div>
<div class='l-inline-col'>
<%= search_field_tag :search, params[:search] %>
</div>
<div class='l-inline-col' style='width: 100px;'>
<%= submit_tag submit_text %>
</div>
</div>
<% end %>
</div>
您可能需要进行视图调整，不能只对所有字段使用 search term/query:
1.make 请确保您视图中表单内的字段与 Contact 模型中需要搜索的列的名称相同
2.add 每个表单中的一个隐藏字段，因此您可以确定这是哪个搜索（还有另一个选项，但这个选项工作较少）
3.change collection_select 其中用户只能 select 一个字段到 select_tag 为了不搞乱查询构建
每个填充的字段都会传递一个值 - 您可以构建一个散列，包括输入的 column/form-field 及其值，例如 { contact_type: "value1", prospect_strength: "value2" }
之后，您需要使用该散列构建查询并查询数据库
这看起来像这样：
在您看来：
在高级搜索表单中添加这个
<%= hidden_field_tag :search_type, :advanced %>
然后在您的正常搜索中添加这个
<%= hidden_field_tag :search_type, :normal %>
在您的模型中：
def self.advanced_search(values_by_column_name) # values_by_column_name is a hash passed from the controller
tag_list = values_by_column_name.delete("tag_list")
sql_query = values_by_column_name.keys.map { |column| "#{column} LIKE :#{column}" }
sql_query = sql_query.join(" OR ")
values_by_column_name = values_by_column_name.transform_values { |value| "%#{value}%" }.symbolize_keys
relation = Contact.where(sql_query, values_by_column_name)
relation = relation.tagged_with(tag_list) if tag_list
relation
end
在你的控制器中：
ADVANCED_SEARCH_FIELDS = [
:contact_type,
:prospect_strength,
:customer_account_id,
:supplier_account_id,
:company_name,
:name,
:title,
:postcode,
:created_at,
:updated_at,
{tag_list: []},
:assigned_to,
:obsolete,
]
def index
@per_page = params[:per_page] || 20
@tags = ActsAsTaggableOn::Tag.all
if advanced_search?
@contacts = Contact.advanced_search(advanced_search_params)
elsif normal_search?
@contacts = Contact.search(params[:qs], params[:search])
else
@contacts = Contact.all
end
@contacts = @contacts.order(sort_column + ' ' + sort_direction).paginate(page: params[:page], per_page: @per_page)
end
def advanced_search?
params[:search_type] == "advanced" && advanced_search_params.any?
end
def normal_search?
params[:search_type] == "normal" && params[:search].present?
end
def advanced_search_params
@_advanced_search_params ||= params.permit(ADVANCED_SEARCH_FIELDS).select { |_, v| v.present? }.to_h
