I have a tiny but silly problem over here, i have a model action;
def self.price_change_up(network, currency, change )
prices = Prices.where('network = ?', network)
prices.each do |price|
price.send("#{currency}") = price.send("#{currency}") + change
price.save
end
end
but the line
price.send("#{currency}") = price.send("#{currency}") + change
return a syntax error. What could be the problem.
I suppose you want to do this instead:
price = price.send("#{currency}") + change
Your current example is invalid syntax because you are trying to assign something to a value, the return value of price.send("#{currency}") whatever may that be.
price.send("#{currency}") = price.send("#{currency}") + change
This is invalid, you can't use '=' to assign ,In case you are looking to use send with setter
self.send("#{currency}=", prev_curr_value)
In the LHS, you are using price.send("#{currency}"), it calls a method dynamically and will return a value which is again being assigned to same value with some addition change which looks wierd. what are you trying to achieve here, explain with an updated qsn.
