Question

I am trying to implement server side validations, to do that i receive the form values in the variable @value

    @value =  {"prev_school":{"name":"","class":"Nursery"},"sibling": {"name":""}}

    @validate = {"prev_school":[{"name":["is_mandatory","is_alphabets"]}}

In @variable I have defined the methods that need to be called for each field. My question is when I run the following code

     @value.each do |key,val| 
         @validate.each do |k,v|
            if k == key puts v end 
        end     
    end

I am getting an error pointing to the if statement

  syntax error, unexpected tIDENTIFIER, expecting kDO or '{' or '('

Could somebody please help with this.

Cheers! 🙂

You want one of these:

@value.each do |key,val| 
  @validate.each do |k,v|
    if k == key
      puts v
    end 
  end     
end

or

@value.each do |key,val| 
  @validate.each do |k,v|
    puts v if k == key
  end     
end

Your version is a syntax error because Ruby doesn’t know that you mean to end the if between key and puts so it is trying to interpret key puts v as an argument for == but gets confused.
