Error 500: following the book Getting Started with Grails Second Edition by Davis and Rudolf

[proggrammer]

I am new to grail and followinf the book Getting Started with Grails Second Edition by Davis and Rudolf to have a hands-on experience, I am at page: 48, just before bootstraping Data
Initially I was not getting the runner drop down on registration add data page of RegstrationController, but some changes I have done and giving me error.
When I click on New Registration to create data, I get the following Error:
(I dont want to touch any file other than which are in folders model and controller, as I have not touched any other than files under these folders-please give me some sight in the problem or problem's solution.)

Please be more specific to the problem so that someone can assist you.

Like:

1. What is version of grails used?
2. Which plugins did u install?
3. What commands have you used to generate code?
   
4. What extra changes have to made to the code other than what's generated?

By answering the above questions, possibly someone can go ahead and answer.

Thanks and regards,

Assuming the code you are running is here:

https://github.com/scottdavis99/gswg-v2 

The Registration object doesn't have a "name" property:

class Registration {   

  static constraints = { 

    race() 

    runner() 

    paid() 

    dateCreated() 

  } 

   

  static belongsTo = [race:Race, runner:Runner] 

 

  Boolean paid 

  Date dateCreated 

} 

Perhaps you meant to say "registrationInstance?.race?.name" instead?

I updated the example to the latest Grails release. This should get you going past the compilation errors.

My fork: https://github.com/bond-/gswg-v2

Pull request: https://github.com/scottdavis99/gswg-v2/pull/6

Assuming the code you are running is here:

The Registration object doesn't have a "name" property:

class Registration {   

  static constraints = { 

    race() 

    runner() 

    paid() 

    dateCreated() 

  } 

   

  static belongsTo = [race:Race, runner:Runner] 

 

  Boolean paid 

  Date dateCreated 

} 

Perhaps you meant to say "registrationInstance?.race?.name" instead?

Like:

1. What is version of grails used?
2. Which plugins did u install?
3. What commands have you used to generate code?
   
4. What extra changes have to made to the code other than what's generated?

By answering the above questions, possibly someone can go ahead and answer.

Hi Ravi,

Sorry that I missed your initial post. There have been a few breaking changes to our example as Grails matures and our book remains fixed in time. It sounds like your mailing list-mates got you moving forward again.

It's funny -- I still get the occasional outraged email from readers of Practically Groovy and Mastering Grails, upset about articles written in the 2004/2005 timeframe. (I'm not suggesting that your email was outrageous or out of line in any way -- just commenting on the nature of writing about fast moving, ever-evolving technology like Groovy and Grails.)

There are lots of things that conspire against books keeping pace with the technology they describe -- lack of author time is the biggest culprit, but also publishers, editors, copywriters, book-sellers (Amazon, et al). Even the tool we used to write the book -- Microsoft Word (ugh!) -- is an impediment to rapidly incorporating changes. There are lots of hidden moving parts to publishing a book that contribute to the velocity mismatch -- even a free one, even a PDF-only one.

Some authors (and publishers) try to be vague about the version number of the technology they are writing about in an effort to extend the shelf life of the prose. As you can tell in Chapter 2, I mention explicitly that the book was written using Grails 1.2. With Grails 2.1 right around the corner, I'm pleased with how well the book still holds up, but it definitely is in need of some renovation. 

Jason and I are in the early stages of rolling out the 3rd edition of the book in a way that will allow us to be more agile as the technology inevitably changes.  Keep your eyes open for an announcement coming Real Soon Now. 

Thanks for reading the book, and I hope that you enjoy your time with Grails as much as Jason and I did when we wrote the book. 

Cheers,

s

Scott Davis

Hi Scott,

No offense with the old example, I understand. BTW I wasn't the initiator of the post :p and pull request was submitted by me.

Hi Ravi,

Sorry that I missed your initial post. There have been a few breaking changes to our example as Grails matures and our book remains fixed in time. It sounds like your mailing list-mates got you moving forward again.

It's funny -- I still get the occasional outraged email from readers of Practically Groovy and Mastering Grails, upset about articles written in the 2004/2005 timeframe. (I'm not suggesting that your email was outrageous or out of line in any way -- just commenting on the nature of writing about fast moving, ever-evolving technology like Groovy and Grails.)

There are lots of things that conspire against books keeping pace with the technology they describe -- lack of author time is the biggest culprit, but also publishers, editors, copywriters, book-sellers (Amazon, et al). Even the tool we used to write the book -- Microsoft Word (ugh!) -- is an impediment to rapidly incorporating changes. There are lots of hidden moving parts to publishing a book that contribute to the velocity mismatch -- even a free one, even a PDF-only one.

Some authors (and publishers) try to be vague about the version number of the technology they are writing about in an effort to extend the shelf life of the prose. As you can tell in Chapter 2, I mention explicitly that the book was written using Grails 1.2. With Grails 2.1 right around the corner, I'm pleased with how well the book still holds up, but it definitely is in need of some renovation. 

Jason and I are in the early stages of rolling out the 3rd edition of the book in a way that will allow us to be more agile as the technology inevitably changes.  Keep your eyes open for an announcement coming Real Soon Now. 

Thanks for reading the book, and I hope that you enjoy your time with Grails as much as Jason and I did when we wrote the book. 

Cheers,

s

Scott Davis

I updated the example to the latest Grails release. This should get you going past the compilation errors.

Assuming the code you are running is here:

https://github.com/scottdavis99/gswg-v2 

The Registration object doesn't have a "name" property:

class Registration {   

  static constraints = { 

    race() 

    runner() 

    paid() 

    dateCreated() 

  } 

   

  static belongsTo = [race:Race, runner:Runner] 

 

  Boolean paid 

  Date dateCreated 

} 

Perhaps you meant to say "registrationInstance?.race?.name" instead?

Please be more specific to the problem so that someone can assist you.

Like:

1. What is version of grails used?
2. Which plugins did u install?
3. What commands have you used to generate code?
   
4. What extra changes have to made to the code other than what's generated?

By answering the above questions, possibly someone can go ahead and answer.
