I'm trying to get the content out of
<p>
<strong>Some headline</strong>
Some text here ...
</p>
I want to store the "some text here ..." in a NSString.
My XPath query looks like this
#"//div[#class='articleInfo']/div[#class='readMore description']/div[#class='readMoreContent']/p"
but that is returning null.
Please help!
if you have something like this:
<div class="articleInfo">
<div class="readMore description">
<div class="readMoreContent">
<p>
<strong>Some headline</strong>
Some text here ...
</p>
</div>
</div>
</div>
then yours xpath should work:
//div[#class='articleInfo']/div[#class='readMore description']/div[#class='readMoreContent']/p/text()
Also as #San said, can be typo. I see you have space here "readMore description", but not here "readMoreContent"

Is it possible to pass a fragment to a message expression in Thymeleaf? I want to re-use fragments for creating links in messages.
My fragment looks something like this:
<div th:fragment="link(url, text)" th:remove="tag">
<a th:href="#{${url}}"><span>${text}</span></a>
</div>
and I have a message like that:
home.welcome=Hello User! See new content at {0}.
Now I want to pass the evaluated fragment to the message expression (pseudo-code):
<p th:utext="#{home.welcome(${link:: link(url='myUrl', text='myText')})}"></p>
The resulting HTML should look like this:
<p>
Hello User! See new content at <span>myText</span>.
</p>
I discovered Fragment expressions introduced in Thymeleaf 3 but I'm not sure if they are the way to go.
You can try th:with.
Call fragments like so
<div th:include="fragments/common :: link" th:with="url='www.google.com', text='Click Me'"></div>
This is your fragment
<div th:fragment="link" th:remove="tag">
<a th:href="#{${url}}"><span th:inline="text">[[${text}]]</span></a>
</div>
This is the HTML you will get
<div>
<a href="www.google.com">
<span>Click Me</span>
</a>
</div>
I am currently working on a project that requires me to create a (real) estate agent website. I have imported an XML list with all the properties and created the database, but when I go to create a properties list and insert the first image for each property, it creates two images (one for each property in the list) and assigns both images to each property.
The code is:
<% #properties.each do |property| %>
<div class="row">
<div class="col-sm-12">
<div class="row">
<div class="col-sm-3">
<% property.pictures.each do |picture| %>
<% if picture.name.eql?('Photo 10') %>
<img src="<%= picture.url %>" class="img-responsive center-block"/>
<% end %>
<% end %>
</div>
<div class="col-sm-9">
<h4><%= property.advert_heading %></h4>
<p><%= property.main_advert %></p>
</div>
</div>
</div>
</div>
<% end %>
The html output is:
<div class="row">

To me it seems that rails is looping throught the property.picture.each twice (or I'm guessing more if I had more properties) and inserting the output twice but I can't see why.
Many thanks
It looks like you have duplicate pictures with a name attribute of 'Photo 10'. Use your rails console to run a query to confirm this.
Picture.where(name: 'Photo 10').count
How many records are returned? Is your expectation that each property would have one picture with a name of 'Photo 10'? If so you you should expect to have as many pictures returned as properties, if not then you have duplicate entries with the name 'Photo 10' for each property. which brings me to my next point.
You should normalize your database. The fact that you are relying on a non unique attribute, and that there are multiple picture entries that point to the same url tells me that. You are also creating a lot of unnecessary picture entries in the picture table. Instead, I'd create a join table between between properties and pictures, maybe called PropertyPictures. For each unique picture url, create one entry in the Picture table. For each property that uses a picture, create an entry in the join table with that property_id and the desired picture's picture_id. This will help in case your pictures change. As you have it now, if one picture url changes it doesn't change in all places, even if it should. As far as your view goes, now that you have a unique and consistent picture_id, use that, it will be impossible to have duplicates. Also, instead of pulling all pictures, just get the one you want. You could write a method in your property model to do this. It might look like this:
def special_picture
pictures.where(id: 1)
end
And in your view:
<% #properties.each do |property| %>
<div class="row">
<div class="col-sm-12">
<div class="row">
<div class="col-sm-3">
<img src="<%= property.special_picture.url %>" class="img-responsive center-block"/>
</div>
<div class="col-sm-9">
<h4><%= property.advert_heading %></h4>
<p><%= property.main_advert %></p>
</div>
</div>
</div>
</div>
<% end %>
`
If you're only wanting the first image for each listing, why are you looping through all pictures for each listing?
You could do this instead:
<div class="col-sm-3">
<img src="<%= property.pictures.first.url %>" class="img-responsive center-block"/>
</div>
My text is overflowing within a span element which has the class: form-control
Code:
<div class="row">
<div class="form-group col-sm-12">
<label>Notes:</label>
<span class="form-control"><%= #stuff.notes %></span>
</div>
</div>
And when #stuff.notes has a lot of text, it overflows like this:
I did look at this question, as well as this ticket within bootstrap. I am still having trouble coming up with a solution.
Update:
I realized I could use a form helper (even though it isn't a form) like this:
<div class="row">
<div class="form-group col-sm-12">
<label>Notes:</label>
<%= text_area_tag :notes, #complaint.notes, {class: "form-control", disabled: "disabled"} %>
</div>
</div>
Which renders it like this:
But I don't like how the disabled html attribute grays out the box and mutes the text. It makes it difficult for the user to read.
You could use a basic panel to get a similar feel. See Bootply Here
<label>Notes:</label>
<div class="panel panel-default">
<div class="panel-body">
Basic panel example
</div>
</div>
And if you really want to match the look of the form-control class, you could add a custom .inset-box-shadow class which would override the box shadow on the panel and give it that formy look. That may confuse users though, they may want to click and type in it.
Question about Rails4, I trying to retrieve the "Find Stuff" variable, in the erb form. This
is a search field, using zurb foundation - so the extra styling annotations floating around.
I don't have a model as this is just a form for reading the search input field - which is
in the tag, with placeholder as "Find Stuff".
To use normal Rails4 terminology, I would
like to pass the value of the "Find Stuff" field to the salutation controller, and I tried
many ways, but was unsuccessful, when I used render params[:post].inpect, it shows nil -the
variables that I pass to the controller, on clicking on the "Search" link_to, link. I tried adding an id field to the tag, and that too showed nil on render params[:post].inspect.
Any help, thanks in anticipation.
hello.html.erb form below.
<html>
<body>
<nav class="top-bar" data-topbar>
<ul class="title-area">
<li class="name">
<h1>Hello World!</h1>
</li>
<li class="toggle-topbar menu-icon"><span>Menu</span>
</li>
</ul>
<ul class="right">
<li class="has-form">
<div class="row collapse">
<div class="large-8 small-9 columns">
<input type="text" placeholder="Find Stuff" >
</div>
<div class="large-4 small-3 columns">
<%= link_to "", :controller =>
'salutation', :action =>'hello',
:class=>"alert button expand" %>
</div>
</div>
</li>
</ul>
</section>
</nav>
</body>
</html>
Controller follows
Salutation Controller follows
class SalutationController < ApplicationController
def new
#test = ''
end
def hello
#message = 'Hello World!'
#test = params[:Find_Stuff]
end
end
Wrap your search box in a form element, give your input a name and away you go. You can use the rails form helpers as well - see http://guides.rubyonrails.org/form_helpers.html which has a nice intro to creating a search form
<div class="row collapse">
<%= form_tag("/salutation/hello", method: "post") do %>
<div class="large-8 small-9 columns">
<%= text_field_tag(:find_stuff) %>
</div>
<div class="large-4 small-3 columns">
<%= submit_tag("Search") %>
</div>
<% end %>
</div>
Further to #slapthelownote's answer, the reason you're getting an error is because you're not passing any params to your controller
We've got something like what you want working at http://firststopcosmeticshop.co.uk (top search box) -- using a form_tag
If you want to see live code, I'll be happy to post!
Params
Using a form allows you to set various variables & then submit them to the controller as you've set them. I'd recommend using the form in the other answer, but to understand how it works, you need to read up on the Rails forms tutorial
Basically, the params hash is populated in the middleware of Rails -- from any data sent by HTTP to your backend
With links, you can only send GET params (domain.com/route¶ms=value), whilst with HTML forms, you can set POST params which are passed through the browser (not the URL)
Thanks for reading. Super frustrated (and maybe missing something fundamental, I've never been great with Nokogiri)
In short - I have a source:
<div class="schedule-page">
<h3>Sunday, September 1, 2013</h3>
<table class="views-table cols-1 schedule-table">
<div class="game">Game 1</div>
<div class="game">Game 2</div>
</table>
<h3>Sunday, September 7, 2013</h3>
<table class="views-table cols-1 schedule-table">
<div class="game">Game 1</div>
<div class="game">Game 2</div>
<div class="game">Game 3</div>
</table>
<!--and so forth.... -->
</div>
I am able to iterate through the source, grab each day and X number of games, and create the container for each day and fields for each game.
<% #schedule_array.each do |a_game| %> #
<div class="game-info">
<div class="date"><%= #the_date %></div>
<div class="single-game"> # this pulls info for each game, works fine.
<div class="game-home"><%= a_game.css('.field-home-team').text %></div>
<div class="game-score"><%= a_game.css('.field-score').text %></div>
<div class="game-away"><%= a_game.css('.field-away-team').text %></div>
<div class="game-time"><%= a_game.css('.field-game-date-start-time').text %</div>
</div>
</div>
<%end%>
But I really don't know how to retrieve the original date (h3) from the source and parse it in such a way so that I can use it as shown above.
I've tried a dozen variations of the example shown under Moving Nodes, here:
http://nokogiri.org/tutorials/modifying_an_html_xml_document.html
But nothing's working. Can anyone tell me the correct way to handle this? My method is gibberish and I'm not sure it's helpful to put it up.
I assume #schedule_array is coming from something like #schedule_array = Nokogiri::HTML( html_contents).css('.schedule-table').
In which case, you need to traverse back to the parent and go back to it's previous sibling and get the value:
game_date = a_game.parent.previous_element.text
So in your particular case, that line can be:
<div class="date"><%= a_game.parent.previous_element.text %></div>
