render in rails with collection is printing thrice

Question

I am using Mongodb with ROR . This is the command:

<%= render partial: "show", collection: @h %>

Where @h is

@h=[
  {"folder"=>"Default", "weight"=>"100.0", "stocks"=>[
    {"id"=>"id1", "name"=>"Ajanta Pharma Ltd.", "weight"=>"57.0"},
    {"id"=>"id11", "name"=>"Avanti Feeds Ltd.", "weight"=>"5.1"}, 
    {"id"=>"id34", "name"=>"MPS Ltd.", "weight"=>"2.5"}, 
    {"id"=>"id89", "name"=>"Poly Medicure Ltd.", "weight"=>"3.7"}]}, 
  {"folder"=>"low margin", "weight"=>"0.0", "stocks"=>[
    ]}, 
  {"folder"=>"fjf", "weight"=>"0.0", "stocks"=>[
  ]}
]

Suppose my _show.erb is this

i am line

The output i am getting is i am linei am linei am line actually no. of times the folder in @h * content in _show.erb If I change @h to this

@h=[
  {"folder"=>"Default", "weight"=>"100.0", "stocks"=>[
    {"id"=>"id1", "name"=>"Ajanta Pharma Ltd.", "weight"=>"57.0"},
    {"id"=>"id11", "name"=>"Avanti Feeds Ltd.", "weight"=>"5.1"}, 
    {"id"=>"id34", "name"=>"MPS Ltd.", "weight"=>"2.5"}, 
    {"id"=>"id89", "name"=>"Poly Medicure Ltd.", "weight"=>"3.7"}]}, 
  {"folder"=>"low margin", "weight"=>"0.0", "stocks"=>[
    ]}` 
]

Then it gives i am linei am line as folder are 2 why it is happening as only want one time output irrespective of no. of folders . How can I do that?

are the tick marks around the array in `@h` there in your code or just in the post? — dax, Sep 25 '13 at 11:07

Done , actually When you pass a collection to a partial via the :collection option, the partial will be inserted once for each member in the collection:

so I used this: <%= render partial: "show", object: @h %>
