Rails在Ruby on Rails中生成模型错误

Question

I am building a new RoR app and i had tried to create a new model like below.

rails generate model Pic title:string description:text

But I keep on getting these errors always and I tried installing many methods like installing gems ,updated the gems etc.

PS : I am trying install the older version of the gems. Is that creating a problem?

But none of it gave me the results. Please help me with this.

PPS : I am an absolute beginner to ruby. So please help me by giving solution with good reason. Thanks in Advance.

Answer 1

Hi seems like you have issues with your simple_form gem,try to remove from gem file and add gem 'simple_form' and run bundle install after this step run rails generate simple_form:install for creating config file for simple form. Try this it may help you out.

Answer 2

As @Navneet pointed out generating a config file can also be used for configuration and it also works pretty well.

Another thing i found was , Here the gems used were older version. That created a compatibility issue (since it was not configured accordingly). So by replacing the gems with current version or stable ones , you can get rid of this problem.

1. Go to rubygems.org
2. Search for the gems and check whether its the latest version
3. If not, Replace the line of corresponding gem in Gemfile with newest one.
