This Map in Ruby doesn't care about my if statement-CodePudding

So, I have this

def userposts
    posts = Post.where(user_id: params[:id])
    postnums = posts.map {|i| i.id }
    postsWithInfo = posts.map{|i| {
            post: i,
            recipe: i.recipe,
            recipepic: rails_blob_path(i.recipe.pic) if i.recipe?,
            pics: i.pics.map{|p| rails_blob_path(p) }
    }}
    render json: {posts: postsWithInfo}, status: 200
end

recipe is null if there's no recipe, and that's what I want, but the problem is that recipepic is crashing the thing if i.recipe is null, and that if statement is doing nothing to stop it. Is there a way I can make it so that this works?

The error I get is

/home/dan/code/projects/project5/backend/app/controllers/posts_controller.rb:27: syntax error, unexpected `if' modifier, expecting '}'
...ails_blob_path(i.recipe.pic) if i.recipe?,

...ath(i.recipe.pic) if i.recipe?,

}}
^

try this way

postsWithInfo = posts.map do |i| 
  {
    post: i,
    recipe: i.recipe,
    recipepic: i.recipe? ? rails_blob_path(i.recipe.pic) : nil,
    pics: i.pics.map{|p| rails_blob_path(p) }
   }
end
