ransack

问题 I am currently experimenting using the ransack gem to conduct a search on a model in Rails. As it stands I am using the basic setup. Controller: def index @q = Person.search(params[:q]) @people = @q.result(:distinct => true) end View: <%= search_form_for @q do |f| %> <%= f.label :name_cont %> <%= f.text_field :name_cont %> <%= f.submit %> <% end %> I have managed to find lot of information about conducting searches on multiple fields, however, I haven't managed to find anything to help me to

问题 I've been wracking my brain over this but can't get it. I feel like the answer is probably obvious. What I'm trying to do is the following: I have an index controller which lists a series of Jobs which I can search using Ransack. Each job has a completion date which either has a date in it or is null (unfinished). Currently, the search itself works great. I would like to make it so that the index page loads up showing only the unfinished work, but I also want it to work so that when someone

问题 I have a recipe model which has_many ingredients and each ingredient belongs to an item. In my advanced search form, I would like a user to select multiple ingredients and let Ransack find a recipe that contains all the ingredients selected by the user. I tried the following searchfield: = f.collection_select(:ingredients_item_id_in, Item.all, :id, :name, {}, {multiple: true}) But logically, this results in all recipes being shown that contain any of the selected ingredients. changing

问题 Using the 'eq' predicate with a blank value, Ransack will cancel out that predicate. Which is obviously handy to have an "All" option in your select. But what if I want to add an option in my <select> for null values too ? In order words how to produce the SQL query SELECT * FROM spree_orders WHERE order_cycle_id = NULL using the 'eq' predicate. My test code (with results) is below. What I would like is to filter out the Order s where order_cycle_id == nil Spree::Order.search(order_cycle_id

问题 I'm using Ransack to allow advanced searching on my users. Currently, the users have first_name , middle_name , and last_name columns. Here is my code: .field = f.attribute_fields do |a| = a.attribute_select ... How can I have a custom one called 'Name', that lets the user search through all three of the columns mentioned above? Note I would still like to keep the remaining attributes as options as well, such as email, phone number, etc. Please keep this in mind when determining an answer.

问题 I have a Ransack form on a project I inherited that looks like this: <%- ransack_form_options ||= {} -%> <%- search_field_options ||= {} -%> <%- search_field_options.merge! autocomplete: "off", id: "q" -%> <div class="search-form"> <%= search_form_for(@q, ransack_form_options) do |f| %> <%= f.text_field search_on, search_field_options %> <%= f.submit 'Search' %> <%= button_tag '', class: 'cancel-search' %> <% end %> </div> The value of search_on is student_first_name_or_student_last_name_or

问题 Is HABTM supported by Ransack? Having the models: Shop HABTM Categories Category HABTM Shops Can I use ransack to search a Shop by a single category? What does the form look like? 回答1: I think the field you're trying to use would be :categories_id_eq Usage would be something like this <%= f.label :categories_id_eq, "Category" %> <%= f.collection_select :categories_id_eq, Category.order(:title), :id, :title %> 回答2: You should be aware that there are gotchas: while this workds fine :categories

问题 I have a search form in the header of my app and I would like to use this search form to search through multiple models within the application. For example a request like /search?q=rails should trigger a search through multiple models like Work , Project , User and their defined attributes. I wanted to use Ransack because I already use it on the Work model in a different area of the app. I think I don't quite understand Ransack yet and the documentation always points out that you have to

问题 I get a strange error when trying to run a global autocomplete search across multiple models in my rails App and leveraging the easy-autocomplete jquery library along with the ransack gem for search. Specifically, I believe the error is in my navbar page as I get this error when I try to run a query- undefined method form_with for #<#<class:0x007f875a6f8b58>:0x007f87600e0aa8> I decided to hack away and switch form_with for form_tag but then I get an error on the line immediately below
