Hi all!
I have running rails3 application (using ruby 1.9.2p0 on Ubuntu). I have installed rails-erd (0.3.0).
I've made all migrations and all rebuild my schema.rb and i run all my tests but after i try to run rake erd it gives me error...
Loading Active Record models...
Generating Entity-Relationship Diagram...
rake aborted!
Table '.. some table name ...' doesn't exist
(See full trace by running task with --trace)
Why it wants to run table that does not exist? How can i avoid this?
Platform:
OS: Mac OS X
Ruby: 1.9.3
Rails: 3.0.5
Graphviz: 2.30.1
Got error:
undefined method
isolate_namespace' for Erd::Engine:Class`
I am having the same problem as #6 but answers given there didn't help, I am not using kaminari, using Rails 3.2.12
Here's output of commands
$ rails c

Hi,
This libraery is very good to use but there is some issue which fine while using this library.
I am get any output based on only, exclude options.
I have use this rake command from my rails application root directory.
bundle exec rake erd title='ContractPort ER Diagram' exclude="StatusInfo, Setting"
Kindly replay and fix the issues ASAP.
just for documentation, the bug caused by the clickatell gem and fixed by removing it
also could work around it with this monkey patch
class RailsERD::Domain::Specialization
DumbErd = Struct.new(:name) do
def generalized?; false; end
end
def initialize(domain, generalized, specialized) # @private :nodoc:
@domain = domain
@generalized = generalized || DumbErd.new('unknown gen')
@specialized = specialized || DumbErd.new('unknown spe')
end
end
also, fixed a bug for class with no table in an association (for whatever reason). Putting this here until I make a Pull Request
class RailsERD::Domain::Relationship
def foreign_key_required?(association)
if association.active_record.table_name && association.belongs_to?
column = association.active_record.columns_hash[association.send(Domain.foreign_key_method_name)] and !column.null
end
end
end

Hi, the "rake erd" task returned the following message to me:
rake aborted!
No such file to load -- json/objects
So i resolved the problem with:
Gemfile
gem "ruby-json"
$ bundle install
Need this to be added to installation documentation?
Thanks.
Even if I am generating a ERD for only one model (using only= option), the Liquidator model shows up in the diagram. I don't have a model called Liquidator at all. Where did it come from?
It seems this Liquidator class only shows up when polymorphism=true is set.
When you mount an engine that contains models, the models are not recognized and an error is thrown.
In my case, we created a rails 3.1 mountable plugin called nms-cmdb and we are getting the following error output when running the 'rake erd' command:
$ rake erd --trace

Hi,
My projects use Datamapper http://datamapper.org/ instead of ActiveRecords,
will you integrate this ORM one day ?
Thanks for the gem.

==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.
Mac OS X already provides this program and installing another version in
parallel can cause all kinds of trouble.
The Cairo provided by Leopard is too old for newer software to link against.
Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:
LDFLAGS: -L/usr/local/Cellar/cairo/1.10.2/lib
CPPFLAGS: -I/usr/local/Cellar/cairo/1.10.2/include

Lastly, using filetype=dot creates a .dot file, but there are no diagrams inside - just a bunch of confusing text and not helpful text.
Hi,
I'd like to try to generate Yuml code for a Rails 3 project, such as in the example you show here http://rails-erd.rubyforge.org/doc/classes/RailsERD/Diagram.html But I don't get where the code needs to go, or how I'm supposed to call it. Am I supposed to fork the code and add the YumlDiagram class in something like rails-erd / lib / rails_erd / diagram /yuml.rb and if so, where do I call YumlDiagram.create from?
Thanks
Exception below. Unfortunately I cannot share the full model. But any pointers to diagnose or workarounds are appreciated. Thanks.

when I am running rake erd this is giving me the error Active Record was not loaded...please help
I have a Rails app with some 150 or so activerecord models. Neither vertical or horizontal orientation work well since there will be so much overlap between different lines since the output will either be absurdly long or absurdly high.
I believe a square option would work a lot better.
Here is what my web page gives as an error:
NoMethodError in Users#show
Showing /home/ubuntu/rails_projects/sample_app/app/views/users/show.html.erb where line #2 raised:
undefined method `name' for nil:NilClass

Show session dump
My code is the following for the controller:
class UsersController < ApplicationController
def show
@user = User.find_by_id(params[:id])
end
def new
end
Here is my show.html.erb
<% provide(:title, 'User') %>
<%= @user.name %>
And i'll add that my page doesn't even get the title its supposed to.
any idea on what I should change?
Thanks for such a great gem. I've used it regularly for a while now.
My most recent project involves postgis geographic columns. I think the output is messing up the graphviz transition to pdf.
I think the dot file generates fine. When I run
dot -Tps /home/adam/Desktop/sitata.dot -o /home/adam/Desktop/sitata.ps
I receive the following error:
Error: /home/adam/Desktop/sitata.dot:73: syntax error near line 73

My schema for the table looks like:

t.datetime "created_at"
t.datetime "updated_at"
end
and I am using the rgeo and activerecord-postgis-adapter gem
Has anyone else experienced this issue?
Thanks!

Hi,
rake doesn't seem to know about the erd task:
$ rake erd
rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!
Don't know how to build task 'erd'
(See full trace by running task with --trace)
I've also tried this with rake 0.8.7, and aside from the deprecation warning disappearing nothing changed.
This is my Gemfile:
$ cat Gemfile
source :rubygems
group :development do
gem "rails-erd"
end
And bundle claims it's all installed correctly:
$ bundle install
Using activesupport (3.0.9)
Using builder (2.1.2)
Using i18n (0.5.0)
Using activemodel (3.0.9)
Using arel (2.0.10)
Using tzinfo (0.3.29)
Using activerecord (3.0.9)
Using ruby-graphviz (0.9.21)
Using rails-erd (0.4.5)
Using bundler (1.0.15)
Your bundle is complete! Use bundle show [gemname]
to see where a bundled gem is installed.
$ bundle show rails-erd

I'm on OS X 10.6.7 + graphviz 2.26.3 installed via homebrew. Although I can generate .png fles without problems I'm unable to do the same with pdf. Heere is what I get:
Saving diagram failed!
Graphviz produced errors. Verify it has support for filetype=pdf, or use filetype=dot.
Original error: Format: "pdf" not recognized. Use one of: canon cmap cmapx cmapx_np dot eps fig gd gd2 gif gv imap imap_np ismap jpe jpeg jpg plain plain-ext png ps ps2 svg svgz tk vml vmlz vrml wbmp xdot
Any clue?
It just chills here for hours and the pdf if empty

I have used erd in the past and has been very effective. I have just been assigned to a new app, so thought I would use ERD to orient myself. I don't know if it makes a difference, but I am using the apartment gem cited in the title.
I invoked:
rake erd orientation=vertical file_name='transcript' title='Transcript' attributes=false only='user,transcript,report_card,section_report'
And got the following error:

how can I show the id too ? And how can I show the tablenames ?

There has not been a gem release since mid-April. There have been some significant changes since then. Please ship these in a new gem version.
Thanks!
Hello
already installed that gem and the error still appears... Any ideas?
Thank you
I'm using rails-erd 0.4.3

It says I have 0 models but running ls -1 app/models/ | wc -l

Hi,
I'm having this problem when I run ERD as a rake task in a Rails project. Running erd
works fine, it generates the correct erd.pdf. However, when I run rake erd

Tasks: TOP => erd => erd:generate
The weird thing is that it used to work until a few commits ago. I went over the commits and I saw that I only changed one model class. I reverted the change to that model class and it still gives the same error. ERD only scans the models right?
After running:
$ rake erd --trace
I get this:

It does not tell me which model it is processing when it fails. I'm running rails 3.1.1 and rail-erd 0.4.5.
Also, is there any way to include/exclude particular models from the diagram? I didn't see one in the docs.
If we have any activeresource class in the models and throws an exception
If I run with inheritance=false, everything looks fine:
Loading application environment...
Loading code in search of Active Record models...
Generating Entity-Relationship Diagram for 21 models...
Done! Saved diagram to ERD.pdf.
If I set inheritance=true, however, I get this:

Graphviz produced errors. Verify it has support for filetype=pdf, or use filetype=dot.

Original error: 2013-10-30 00:57:12.159 dot[43036:d07] CoreText performance note: Client called CTFontCreateWithName() using name "Arial Bold" and got font with PostScript name "Arial-BoldMT". For best performance, only use PostScript names when calling this API.
Replacing the font names with the PostScript names solves the issue. I'm not sure if this is backwards compatible, so I'm not pushing my code. I will, gladly, once this is discussed.
I used rails erd to try to generate ERD for the latest Spree edge code:

The generated diagram only contains a few models, namely: ProductGroup, Product, Variant, User, Order, LineItem
I have a file '/ligne_commande.rb ' and erd tell me :
Expected ..../app/models/ligne_commande.rb to define Ligne_commande
Which is not the rails convention. It should expect LinegneCommande.
I had the problem described in #12, so I did
$ brew uninstall cairo pango graphviz
$ brew install cairo pango graphviz
$ rake erd

Original error: cairo: out of memory
Tasks: TOP => erd => erd:generate
(See full trace by running task with --trace)
When installing both cairo and libiconv I got similar messages:
This formula is keg-only, so it was not symlinked into /usr/local.
Mac OS X already provides this program and installing another version in
parallel can cause all kinds of trouble.
The Cairo provided by Leopard is too old for newer software to link against.
Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:
LDFLAGS: -L/usr/local/Cellar/cairo/1.10.2/lib
CPPFLAGS: -I/usr/local/Cellar/cairo/1.10.2/include
I'm running Mac OS X 10.7 (Lion) and I wanted to know if this might be the issue, and were could I start looking for fixes. Thanks for making this great software.
Can i to configure to show plugins relationships?
Thanks.
I created a sample Rails app. I generated two models, A and B, and a relationship model called Rel.
Then I added a many-to-many association between A and B using has_many :through
, which connects A and B via the Rel model.
Here's some code:
# models/a.rb
class A < ActiveRecord::Base
has_many :rels
has_many :bs, through: :rels
end
# models/b.rb
class B < ActiveRecord::Base
has_many :rels
has_many :as, through: :rels
end
# db/migrate/xxx_create_rels.rb
class CreateRels < ActiveRecord::Migration
def change
create_table :rels do |t|
t.belongs_to :a, index: true
t.belongs_to :b, index: true
t.timestamps
end
end
end
When using rails-erd
, I expect to get a many-to-many indirect (as stated on the docs) association between A and B, which means a dotted line with arrows at both ends between A and B (as if I used HABTM), and a solid line with between A and Rel and between B and Rels with an arrow pointing to Rel (being a one-to-many association).
Here's what I get:
The dotted line points from A to B, while A and B join the association in a perfectly symmetric way.
It is possible to get rails-erd to create a subset of an application's models? On very large projects, the output of erd-rails can be almost unintelligible due to "cables" where many relationships visually merge together and cross-cross all over the diagram.
For example, it would be nice to say something like "rake erd MODELS=foo,bar,baz" and have the tool only build an ERD for those three models. I don't know how difficult this is, but it's a feature I really wish I'd had today. :)

I have a class named 'Node'. The dot file generated does not have this class name enclosed in quotes, so dot throws an error and this class isn't added to the PDF. If I manually edit the dot file to add quotes (like so: "Node") and manually run dot then the class does appear in the diagram. It's probably easier to just always enclose class names in quotes.
