How to replace item name to item id before save in database.
This is my controller code
def create
#supplier = Supplier.new(supplier_params)
if #supplier.save
item_code = params[:supplier_item][:item_ids]
item_id = Item.where(:item_code => item_code).pluck(:id)
item_params = params.require(:supplier_item).permit(item_ids: [], location_ids:[], supplier_prices: [])
items = item_params[:item_ids].zip(*item_params.values_at(:location_ids, :supplier_prices))
items.map do |item_id, location_id, supplier_price|
supplier_item = SupplierItem.new({
item_id: item_id,
location_id: location_id,
supplier_price: supplier_price,
supplier_id: #supplier.id
})
supplier_item.save
end
flash[:success] = "New supplier created"
redirect_to supplier_path(#supplier)
else
render 'new'
end
end
So this code now save item_ids["Apple", "Banana"]. But I want to save this in id form which is like this item_ids["1", "3"]
This is my view code
<%= f.label :item, class: 'required'%>
<% items = Item.where(company_id: current_user.company.id)%>
<%= text_field_tag "[supplier_item][item_ids][]", nil, {list: 'browser-item'} %>
<% items.each do |item| %>
<option data-value = <%= item.id %> value = <%= "#{item.item_code} - #{item.name}" %>></option>
<% end %>
So I try this to get item id of the item name
Item.where(:item_code => item_name).pluck(:id)
This one give me all the item id I were selected. So how should I replace this id into the params

I'm making an application where the user can search Amazon (with Vacuum) through my application for books, then be able to record the data of the book to their library.
When you search for a book, it goes through every result and puts each in a thumbnail. In every thumbnail there is a button that opens a modal with a form with hidden tags. When the user clicks the submit button, the book's title is saved into a new book. The only problem is that the title is saved like {:value=>"the title of the book that was saved"}
Here is the part of new.html.erb which has the search box:
<%= form_tag({controller: "books", action: "new"}, method: "get", id: "search-form") do %>
<%= text_field_tag :keywords, params[:keywords], placeholder: "Search for a book", class: "form-control" %>
<% end %>
Here is the part of new.html.erb which has the hidden form:
<% #results.each do |result| %>
…
<%= form_for #book do |f|%>
<%= hidden_field_tag :title, class: 'form-control', value: result.name %>
<%= f.submit "Add book", class: "btn btn-default green-hover" %>
<% end %>
…
<% end %>
Here are the new and create actions in my controller:
def new
#book = current_user.books.build if logged_in?
# Search actions
if params[:keywords]
request = Vacuum.new
request.configure(
aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'],
aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
associate_tag: 'my associate tag is here'
)
keywords = params[:keywords]
params = {
'SearchIndex' => 'Books',
'Keywords'=> keywords,
'ResponseGroup' => "ItemAttributes,Images"
}
raw_results = request.item_search(query: params)
hashed_results = raw_results.to_h
#results = []
hashed_results['ItemSearchResponse']['Items']['Item'].each do |item|
result = OpenStruct.new
result.title = item['ItemAttributes']['Title']
result.url = item['DetailPageURL']
result.image_url = item['MediumImage']['URL']
result.author = item['ItemAttributes']['Author']
result.pages = item['ItemAttributes']['NumberOfPages']
#results << result
end
end
end
def create
#book = #list.books.build(book_params)
if #book.save
flash[:success] = #book.title + "was added to your log."
redirect_to list_path(#book.list_id)
else
render 'books/new'
end
end
I tried to use gsub within book.rb to fix it, but that only changed the text within the flash message and it still saved as {:value=>"the title of the book that was saved"}.
after_create :init
private
def init
puts "Init was called!"
self.title.gsub!('{:value=>"', " ")
self.title.gsub!('"}', " ")
end
How can I change it so that it doesn't save the title with the {:value=>} around it?
I don't think the hidden field tag is right.
<%= hidden_field_tag :title, class: 'form-control', value: result.name %>
Try
<%= hidden_field_tag :title, result.name %>
Your title is being saved as a hash not a string. Use hash accessing methods:
t = title[:value]
puts t #=> "the tile of the book that was saved"
i need update a single record attribute but i can´t. alumno_id is foreign key of model 'alumno'. the code show the records and if submit 'Aceptar' in one record, need a change the attribute estado to 1
in Model
class Postulacion < ActiveRecord::Base
attr_accessible :ramo, :estado, :alumno_id
belongs_to :alumno
end
in View
<h1>Lista de Postulaciones</h1>
<% #postulaciones.each do |p| %>
<% #id = p.id %>
<%= #id %>
<p>
<td><%= Alumno.find(p.alumno_id).full_name%></td>
<td><%='=> '+ p.ramo %></td>
<td><% if p.estado == 0 %>
<%= 'Pendiente =>' %>
<%= form_tag :action => 'aceptar' do %>
<%= submit_tag 'Aceptar' %></p>
<%end%>
<%else%>
<%='=> Aceptado' %>
<%end%>
</td>
</p>
<% end %>
in controller
class ListadoController < ApplicationController
def listar
#postulaciones = Postulacion.all
respond_to do |format|
format.html
format.json { render json: #postulaciones }
end
end
def aceptar
#postulacion = Postulacion.where(id: #id).first #Edit
#postulacion.estado = 1 #Edit
#postulacion.save #Edit
redirect_to "/"
end
end
Error "undefined method `update_attribute' for []:ActiveRecord::Relation"
Thanks
With this code:
#postulacion = Postulacion.where(alumno_id: #id )
You are declaring #postulacion as a collection, not as a single instance. You can fix this by calling .first:
#postulacion = Postulacion.where(alumno_id: #id ).first
Or by using find_by instead of where:
#postulacion = Postulacion.find_by(alumno_id: #id )
One other thing - this code isn't checking for the possibility that the Postulacion instance might not exist. You should add some logic to handle this...
Your #postulacion variable holds ActiveRecord::Relation instead of single ActiveRecord object. Try:
def acceptar
#postulacion = Postulacion.find_by_alumino_id(#id)
# ...
end
or, if you'd be using Rails 4:
#postulacion = Postulacion.find_by(alumino_id: #id)
I'm using Rails3 to build a simple customer information page (in table format). On this page user can edit each customer's detailed information. It's possible for each customer to have multiple records. I use link_to to get to the edit page:
<td class="edit" id="edit">edit
<%= link_to 'edit', :action => :edit, :cust_id => ci.cust_id %>
</td>
edit.html.erb:
<h1>Editing cust</h1>
<%= form_for(#cust_info) do |cust| %>
Customer: <%= cust.text_field :cust_schema %>
<%= cust.submit "Save" %>
<% end%>
In my controller, I have this:
def edit
cust_id = params[:cust_id]
#cust_info = CustInfo.find(:all, :conditions => ["cust_id = ?", cust_id])
end
The customer info page shows right. When I click the edit link, I got the error message:
ActionView::Template::Error (undefined method `cust_info_cust_info_path' for #<#<Class:0x7fb0857ce7b8>:0x7fb0857ca780>):
1: <h1>Editing cust</h1>
2:
3: <%= form_for(#cust_info) do |cust| %>
4: Customer: <%= cust.text_field :cust_schema %>
5: <%= cust.submit "Save" %>
6: <% end%>
app/views/track/edit.html.erb:3:in `_app_views_track_edit_html_erb___102324197_70198065248580_0'
Where does `cust_info_cust_info_path' come from?
EDIT: here is the code in the controller:
class TrackController < ApplicationController
def display
end
def information
end
def customerinfo
#cust_info = CustInfo.find(:all, :order=>"cust_id")
#cust_info.each do |ci|
if ci.upload_freq == 'W'
ci.upload_freq = 'Weekly'
elsif ci.upload_freq == 'M'
ci.upload_freq = 'Monthly'
end
end
end
def edit
cust_id = params[:cust_id]
#cust_info = CustInfo.find(:all, :conditions => ["cust_id = ?", cust_id])
end
end
end
Change #cust_info = CustInfo.find(:all, :conditions => ["cust_id = ?", cust_id])
to
#cust_info = CustInfo.find(cust_id)
I have form that create two objects and save them to database.
I want to do next things:
save data in database (booth objects)
validate fields (I have validation in model)
and if validation fail, I want to populate fields with entered data
edit action for this form
Problems:
If I use #report I get:
Called id for nil, which would
mistakenly be 4 error
(can't find object). I have in controller, in encreate action #report = ReportMain.new and in action that render that view.
When I use :report_main (model name) it works, it save data to database, but I can't get fields populated when validation fails.
Questions:
What to do with this two models to make this to work (validation, populating fields, edit)?
Can you give me some advice if approach is wrong?
My view looks like this:
<%= form_for(#report, :url => {:action => 'encreate'}) do |f| %>
<%= render "shared/error_messages", :target => #report %>
<%= f.text_field(:amount) %>
<% fields_for #reporte do |r| %>
<%= r.check_box(:q_pripadnost) %>Pripadnost Q listi
<%= select_tag('nacinpakovanja',options_for_select([['Drveno bure', 'Drveno bure'], ['Kanister', 'Kanister'], ['Sanduk', 'Sanduk'], ['Kese', 'Kese'], ['Posude pod pritiskom', 'Posude pod pritiskom'], ['Kompozitno pakovanje', 'Kompozitno pakovanje'], ['Rasuto', 'Rasuto'], ['Ostalo', 'Ostalo']])) %>
<%= r.text_field(:ispitivanjebroj) %>
<%= r.text_field(:datumispitivanja) %>
<% end %>
<input id="datenow" name="datenow" size="30" type="text" value="<%= #date %>">
<div class="form-buttons">
<%= submit_tag("Unesi izvestaj") %>
</div>
<% end %>
encreate actin in ReportController:
def encreate
#report = ReportMain.new
#reporte = ReportE.new
#reportparam = params[:report_main]
#report.waste_id = params[:waste][:code]
#report.warehouse_id = Warehouse.find_by_user_id(current_user.id).id
#report.user_id = current_user.id
#report.company_id = current_user.company_id
#report.amount = #reportparam[:amount]
#report.isimport = false
#report.isfinished = false
#report.reportnumber = ReportMain.where(:company_id => current_user.company_id, :isimport => false).count.to_i+1
if #report.save
#reporte.report_main_id = #report.id
else
redirect_to(:action => 'exportnew')
return
end
#reporte.vrstaotpada = params[:vrstaotpada]
#reporte.nacinpakovanja = params[:nacinpakovanja]
#reporte.ispitivanjebroj = #reportparam[:ispitivanjebroj]
#reporte.datumispitivanja = #reportparam[:datumispitivanja]
#reporte.q_pripadnost = #reportparam[:q_pripadnost]
#reporte.datumpredaje = #date
if #reporte.save
redirect_to(:action => 'show', :id => #reporte.id)
else
redirect_to(:action => 'exportnew')
end
end
I think your problem in this case is that you use redirect_to instead of render. When you use redirect_to then you lose all the variables from your current action. I would probably do something like this in your encreate action:
if #reporte.save
render :show
else
render :exportnew
end
When you use render then it will use the variables from the current action but the view from the action you send to the render method. So when form_for is called with the #report variable, it is already populated with the values that was sent to encreate. Just make sure that you use the same variable names in the different actions but it looks like you do that already.
I have the following problem. I have a form which takes input for a "Chart" object. But after processing the form, i wish to display one of the values, and it adds the key of this value.
Class model
class Chart
attr_accessor :title, :series
def initialize(title = nil, series = [])
#title, #series = title, series
end
end
View of form:
<% form_for :chart , :url => { :action => "show" } do |f| %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>...
<% end %>
Chart controller, show method:
def show
#chart = Chart.new(params[:chart])
end
View of show:
<h2><%=h #chart.title %></h2>
Which displays: "title"input_forms_title""
for example: writing in the input form: Economy, prints in the show view: "titleEconomy"
Any ideas?
I have just figured it out. The problem was in the constructor or initialize method. By changing the initialize method to:
def initialize( options = {} )
#title = options[:title]
#series = []
end
It now accepts all params perfectly!
