Maybe. What I am pointing out is that a CMS is a high-level abstraction, and depending on the type of site you are trying to build, it may be a perfect fit for your project. But it also comes with a bunch of features that only make sense if you are trying to build a content-managed site, like a blog or a news site. A lower-level toolkit, like Rails or Django or Symfony, can be used to build almost anything, because it doesn't make any assumptions about what you're trying to do with it. All it does is provide a meaningful level of "plumbing" to allow you to construct a data-driven site. It makes no guesses about what sort of site that would be. If all you need is a CMS, then you can use one and you won't have to build anything. But if what you need (and your initial post made it very clear that this is true) is quite a bit more than what a CMS can provide, then you may want to build from scratch. Using Rails or Django or Symfony means you would't have to REALLY build from scratch, writing your own database access code and template substitution system, for example.
To give you a real-world (metaphorical) example, if someone gave you a truck-load of bricks and portland cement, you could build just about anything with it. But if they gave you a truckload of 36-foot pre-stressed concrete beams, you would have difficulty making the same range of finished projects with it. The pieces are too big to make a fireplace.

Unless the project fits neatly into the pattern of your CMS (f.e. Drupal is perfect if you are building a community-written book, or a magazine, or a corporate Web site with a contact form), then that's going to be the fastest way to the finish line. But the moment you stray from the fall line, you will be skiing in the trees, and often have to un-do the core premises of the CMS in order to build some bit of functionality that you really need.

Hey Guys,A group of guys and myself have been working on a project/business plan to develop a Hotel Concierge application for tablets. We have been working on it for over a year and have hotels here in Chicago that are on board and very interested with our concept. We also are in the works with some large APIs as well as some contracts with some large APIs that want to work with us. Recently our developer had to drop out of the group because he became too busy with his other projects and we have been at a standstill for a couple of weeks. Can anyone provide me some direction on where to find start looking for another developer or if this sounds like an interesting venture and you would like more information please contact me at crcle...@gmail.com.I appreciate any help you can offer.

Thanks, always nice to have some good laughs in the morning :-)
If nothing else, though, shouldn't you simply get the programmers
who'll be involved together to agree on a language/platform??

Unless the project fits neatly into the pattern of your CMS (f.e. Drupal is perfect if you are building a community-written book, or a magazine, or a corporate Web site with a contact form), then that's going to be the fastest way to the finish line. But the moment you stray from the fall line, you will be skiing in the trees, and often have to un-do the core premises of the CMS in order to build some bit of functionality that you really need.

In my situation I have to use EAV-model (MySQL database) to deal with dynamic attributes (for products: color, weight, height and etc.)
Model: Product, Option, Value
So, in this case I have relation: product has many options through values.
It's okay, when I modify and print it.
But what is the best solution for search on them?Do you have to use Mysql for the search side too? Something like elasticsearch is good at searching over that sort of dataset.FredBecause I have to have many inner joins with the same table - values
And each join should have own conditions, for example:option_alias1.name = 'color' AND values_alias1.value = '100'
AND option_alias2.name = 'weight' AND values_alias2.value < '200'
So, I can't do it by join existing relation many times, because I haven't got access to aliases. Should I write raw sql queries or there is more convenient way?
Thank you.

Thanks Robert Walker for response. Well send_sms is the form name only but fckeditor is expecting only models. It is not considering any of the name like
There is a model like student fckeditor works fine with below line
<%= fckeditor_textarea :student, :message,:lang => I18n.locale,:langdir => (rtl? ? 'rtl' : 'ltr') %>
as there is student model and there is no send_sms model I have issue in view but in spite of give the model name to fckeditor in controller which what that value or the text from fckeditor in this way params[:student][:message] I do not get any value in controller. This is what I am facing it.
There is another text box
<%= text_field :send_sms,:subject,:placeholder => 'Subject'%>and when I access params[:send_sms][:subject] I get my params here but not with fckeditor as it expects model name first in place of send_sms but after giving the any model name I can not access my params.

SendSms.The Rails documentation can help you. I have linked to the Rails 4

documentation describing form_for. Rails 4 removed remote_form_for and
instead added the remote functionality to form_for as you can see later
in the docs:

i am using google maps for my project in rails 4, ruby 2, and
gmaps4rails '1.5.6' but the problem is i am not getting marker at center
of the map as well as the zoom in zoom out side bar is also not coming.
If any one have any idea about this problem please reply?
Model Action
acts_as_gmappable
def gmaps4rails_address
html = full_address(city_id,state_id,country_id)
self.location = (location + html)
location
end
def full_address(city_id,state_id,country_id)
city_name = MdmCity.get_city_name(city_id)
state_name = MdmState.get_state_name(state_id)
country_name = MdmCountry.get_country_name(country_id)
html = "#{city_name} #{state_name} #{country_name}"
html
end
Controller Action
def edit_content
@location_json = SeoContent.where(:id =>
params[:id]).first.to_gmaps4rails
end
VIEW
<%= gmaps4rails(@location_json) %>
Issues for me.
1) Zoom In and Zoom out bar is not coming.
2) Marker is not coming at center.
3) How to give Info window.
4) How to raise that address is Invalid, which is not present on google
map (Eg:kdjfkdfhdkfhd)
5) Why this action (def gmaps4rails_address) is calling automatically.
6) I want to call def gmaps4rails_address from update action too how ?
7) Map is coming only one forth ?why
8) Can i show directions on map ?
Thanks

Hello,
This is my first post here! I`m a computer engineering with almost no formation in web Development. What I do know, is software engineering/architecture, Java and C/C++. I also have had some foundation in XHTML/CSS.
So, this said, a friend came to me asking to develop a Website similar to eBay/Amazon/etc., I know it`s a huge project, so i don't want to develop it with SQL, PHP, HTML. I want to use some Modern technology... I`ve read about a few of them:
MVC -> facilitates the development of website by handling all those "complicated" language (SQL, PHP, HTML) and it`s connection automatically by the use of some language:
- Java -> JSF
- Ruby -> RubyOnRails
- Python -> Django
CMS -> facilitates the development of website by templates; in other words, it has many templates of many kinds of websites and those templates can be customized.
- drupal
- joomla
I do know some of the strengths and weakness of each MVC/CMS.... the CMS is faster to develop, but it`s less customizable... From what I`ve heard of my friends project, it`s not a common website, it`ll provide a lot more than eBay/etc. So I`m afraid of using CMS.
Most of all, the project should be modular; in other words, it must be possible to add new tools to the website after its completion.
If anyone has something to add, suggest or ask, please feel free.
Thanks in advance.

newbie disclaimer - i have yet to even start using RoR.......
hello all - i am getting ready to start looking into RoR and was
wondering about how various (and many) jScript frameworks might tie into
RoR.
particularly, i was interested in google-AngularJS, probably because i
notice that google has thrown its mighty weight behind it.
i also saw there was a coffeescript, backbone.js, and a couple dozen
others.
is there one jScript framework that plays best with RoR? is using two
different frameworks counterproductive ?
being the idiot newbie that i am, i am surprised that RoR has not
partnered up with a jScript framework!

In my View I have a list of items in database. By the side of each item
in there is "delete" link.
There is also an AJAX form which allows to create new items. New items
are appended to list by JS.
When submit button is pressed, controller should send back JSON. The
problem is - how to send that "delete" link as a JSON? Since link's html
has some double quotes in it, I dont get valid JSON and my JS crashes.
destroy_link = view_context.link_to('Delete', created, method: :delete,
remote: true, :class => 'minus' )
json = {'plural' =>
created.class.name.pluralize.underscore.downcase,
'singular' => created.class.name.underscore.downcase,
'created' => created
}.to_json
Since I dont know a lot about ajax, propably something is terribly wrong
here?

Doing what you're doing here is good. Look also in the Rails group on LinkedIn. Look around your area for Ruby/Rails users groups. (There's a couple here in Minneapolis, RUM, and Rails MN.)

It is not a routing error, it cannot find the controller. Are you
sure you renamed the controller file and the class correctly? Have
you restarted the server?

Did the db:migrate operation complete successfully? Verify using the command line tool appropriate for the database manager you're using. What step are you at in the Getting Started Guide?

Right - I should have realised that what I was looking at was the DB
stuff - I have found:
.gem/ruby/bundler/gems/devise-4e2cdc2d5b81/lib/devise/models/validatable.rb
and it seems to have some stuff in it that is relevant - I will check
that out.
Thanks,
Phil.

Suppose you have a controller HomeController. It should look like below.
home_controller.rb
class HomeController < ApplicationController # GET /show_message def show_message format.js { render js: "alert('simple output');" } end end
and in your routs.rb file add this line
get '/show_message', 'home#show_message', as: :show_message
and in your view add this line
<%= link_to "Print", show_message_path, remote: true %>
After this when you click on Print link, and AJAX request will be sent to HomeController'sshow_message action and it will display a javascript alert.
For better understanding of AJAX requests in Rails, follow this tutorial - http://www.tutorialspoint.com/ruby-on-rails/rails-and-ajax.htm :)
