ruby on rails - How can I have 2 loops display information in-between each other -

-

i have 2 input fields generated 2 different hashes.

table_head = {"key1"=>"thead1", "key2"=>"thead2", "key3"=>"thead3", "key4"=>"thead4"}  table_content = {"1"=>"column1", "2"=>"column2", "3"=>"column3", "4"=>"column4"}   <%= form_for([@category, @page], url: update_pages_path) |f| %>      <% @page.table_head.each_with_index |(key, value), i| %>       <%= text_field_tag ('header[' + i.to_s + ']'), value %>      <% end%>       <% @page.table_content.each_with_index |(key, value), i| %>       <%= select_tag 'content[' + i.to_s + ']', options_for_select(@category_keys, value), { :multiple => true, :size => 3}  %>     <% end%>    <% end %>

this makes 4 table_head inputs , 4 table_content selects. need them ordered, table head input, table content select, table head input, content select , on. not table head inputs , table content selects.

i fields

 <% @page.table_head.each_with_index |(key, value), i| %>   <%= text_field_tag ('header[' + i.to_s + ']'), value %>    <%= select_tag 'content[' + i.to_s + ']', options_for_select(@category_keys), { :multiple => true, :size => 3}  %>  <% end%>

but default options_for_select value cant put in content field.

how can have fields ordered head, content, head, content etc.. insead of head, head, head, head, content, content etc..

table_head = {"key1"=>"thead1", "key2"=>"thead2", "key3"=>"thead3", "key4"=>"thead4"}  table_content = {"1"=>"column1", "2"=>"column2", "3"=>"column3", "4"=>"column4"}  <%= form_for([@category, @page], url: update_pages_path) |f| %>   <% @page.table_head.zip(@page.table_content).each |head, content| %>     <% head_key, head_value = head %>     <% content_key, content_value = content %>     <%= text_field_tag ('header[' + head_key + ']'), head_value %>      <%= select_tag 'content[' + content_key + ']', options_for_select(@category_keys, content_value), { :multiple => true, :size => 3}  %>   <%end%> <% end %>

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
