I have a Thymeleaf template with a rather complex data- attribute, like so:
<div data-dojo-props="required: true, placeholder:'Foo bar baz', more: stuff" ...>
I'd like to have Thymeleaf provide the placeholder, like so:
<div th:data-dojo-props="placeholder:'#{foo.bar.baz}'" ...>
It doesn't work, of course. I'm supposed to use th:attr like so:
<div th:attr="data-dojo-props=placeholder:'#{foo.bar.baz}'" ...>
Which also doesn't work. As soon as you add a : or ' within the th:attr, the template breaks. I also tried escaping them, e.g. \: and \', and also tried using HTML entities, e.g. &38;, but also didn't work.
So I tried th:prependattr and th:appendattr:
<div th:prependattr="data-dojo-props=placeholder:'"
th:attr="data-dojo-props=#{foo.bar.baz}"
th:appendattr="data-dojo-props='"
...>
But they also can't handle : and ', nor escaping them:
<div th:prependattr="data-dojo-props=placeholder&58;&39;"
th:attr="data-dojo-props=#{foo.bar.baz}"
th:appendattr="data-dojo-props=&39;"
...>
Any way to make this work that I'm missing?
You can use parameters in a Thymeleaf message property for example:
Messages.properties:
dojo.props=required: {0}, placeholder: {1}, more: {...}
dojo.props.required=true
dojo.props.placeholder=Foo bar baz
HTML with message properties:
<div th:attr="data-dojo-props=#{dojo.props(#{dojo.props.required}, #{dojo.props.placeholder})}"></div>
Or if you want to get the values from a object:
<div th:attr="data-dojo-props=#{dojo.props(${dojo.props.required}, ${dojo.props.placeholder})}"></div>
Even selectors work:
<div th:attr="data-dojo-props=#{dojo.props(*{dojo.props.required}, *{dojo.props.placeholder})}"></div>

I'm trying to iterate over a list and pass the current iteration and another model variable to a fragment, but the "other" model variable is always null.
<div th:each="place : ${results.placeResults}" class="col-sm-6 col-xl-4 mb-5">
<div th:replace="fragments/placecard :: placecard" th:with="place=${place},res=${results}"/>
</div> <!-- end for each-->
In the fragment ${res} is always blank.
I figured it out, the th:replace basically makes the th:with have no effect. I changed the code to use th:include and things look better.
There is the structure like:
<div class="parent">
<div>
<div class="fieldRow">...</div>
</div>
<div>
<div class="fieldRow">
<div class="CheckBox">
</div>
</div>
<div>
<div class="fieldRow">...</div>
</div>
<div>
<div class="fieldRow">...</div>
</div>
</div>
In my script I am writing a loop for each of the 4 div's under div[#class='parent'] and aiming to click the checkbox if there is, i.e.
members = page.all(:xpath, '//div[#class='parent'])
members.each do |a|
if **page.has_xpath?(a).find(:xpath, "div[#class='fieldRow']/div[#class='CheckBox']")**
a.find(:xpath, "div[#class='fieldRow']/div[#class='CheckBox']").click
end
end
However I can't look for the correct usage of has_xpath? with xpath including variable.
Please advice? Thank you!
has_xpath? takes an XPath expression (not an element) and returns a boolean (true/false) based on whether there are any elements that match that expression within the current scope - http://www.rubydoc.info/gems/capybara/Capybara/Node/Matchers#has_xpath%3F-instance_method. Since it returns true/false you can't then call find on it. For the example you posted there's no need for XPath or checking for the existence of the elements, just find all the matching elements and call click on them. Something like
page.all('div.parent div.fieldRow div.Checkbox').each { |cb| cb.click }
or
page.all('div.parent div.Checkbox').each { |cb| cb.click }
if the fieldRow class isn't something you really need to check.
Note: this assumes clicking the elements doesn't invalidate any of the other matched elements/change the page.
If you REALLY need to do it with the whole members and looping on them , using XPath, and checking for presence then it would be something like
members = page.all(:xpath, './/div[#class='parent'])
members.each do |a|
if a.has_xpath?(:xpath, ".//div[#class='fieldRow']/div[#class='CheckBox']")
a.find(:xpath, ".//div[#class='fieldRow']/div[#class='CheckBox']").click
end
end
Note: the .// at the beginning of the XPath expressions is needed for scoping to work correctly - see https://github.com/teamcapybara/capybara#beware-the-xpath--trap - which is an issue using CSS selectors doesn't have, so you should really prefer CSS selectors whenever possible.
Feels like a dumb question but I do not get it. How can I do fast string concatenation in Angular 2 Dart templates?
I have a seperate html file for my component lets say my_component.html:
Works:
....
<div id="abc">
{{order.pickupPlace.email}}
</div>
...
Works:
....
<div id="abc">
{{ ((order.pickupPlace.state) ? order.pickupPlace.state+" ":'')}}
</div>
...
Does not work:
....
<div id="abc">
{{"<br/>"+order.pickupPlace.email}}
</div>
...
Does not work:
....
<div id="abc">
{{order.pickupPlace.name+" "+order.pickupPlace.email}}
</div>
...
Have tried to find an answer in the docs here (https://webdev.dartlang.org/angular/guide/template-syntax#!#expression-operators) but no luck.
Of course I could use *ngIf on every element which I output conditionally but is there a way for simple string concatenation?
The best way is to declare a getter inside your Component controller that does the concatenation for you, you will get dart syntax support and the html template will looks cleaner.
String get myConcatenation => "${order.pickupPlace.name}${order.pickupPlace.email}";
<div id="abc">
{{myConcatenation}}
</div>
The last two examples can be made to work easily:
<div id="abc">
<br/>{{order.pickupPlace.email}}
</div>
And:
<div id="abc">
{{order.pickupPlace.name}} {{order.pickupPlace.email}}
</div>
Angular handles this pretty well. If you need some more complicated logic you can move it to the Dart code (but you cannot use HTML there easily).
If you find creating lot of weird logic consider creating more smaller components that can handle this for you.
I'm using a cucumber/ruby/capybara/siteprism framework and I'm having problems identifying elements as either we're missing the ids, names, etc or they create them with a in real time.
I was mainly trying to define some of those elements in a siteprism page object model. For example, I was trying to enter some data in the 'input' field for 'First Name' below:
<div class="control-group">
<label class="control-label" for="input_field_dec_<random_number>">
First Name
<span class="required"></span>
</label>
<div class="controls">
<input id="input_field_dec_<random_number>" class=" span5" type="text" value="" scripttofire="SetUserFirstName('input_field_dec_<random_number>')" required="required" name="input_field_dec_<random_number>" data-val-required="First Name is required" data-val-regex-pattern="^[a-zA-Z0-9_ \-\']*$" data-val-regex="Only alphabetic and numeric characters allowed" data-val="true">
<span class="field-validation-valid help-inline" data-valmsg-for="input_field_dec_<random_number>" data-valmsg-replace="true"></span>
</div>
</div>
Is there a way to pass the label text (eg: 'First Name' - ignoring the spaces around, something like - contains='First Name') and then find the input element inside to set it up?
I was thinking something along the lines of:
element :first_name_field, :xpath, "//label[contains(text()='Continue'])/<and here something to find the input field?>" but cannot figure it out...
Capybara provides a bunch of built-in "selectors" that can be used for this, and you can add your own if you find it necessary. You can see the provided selectors by either building the Capybara docs yourself (rubydocs doesn't run the custom yard code used to generate that part of the docs) or by browsing the file where they are implemented - https://github.com/teamcapybara/capybara/blob/master/lib/capybara/selector.rb#L47
For your original example you can use the :field selector
element :first_name_field, :field, 'First Name'
which will match on the inputs associated label text. For you second example (from the comments) where the input and label have no connection (wrapped or for attribute) you should be able to do something like
element :some_field, :xpath, ".//label[contains(normalize-space(string(.)), 'label text')]/following-sibling::*[1]/self::input"
If you wanted to make that reusable you could add your own "selector" like
Capybara.add_selector(:sibling_input) do
label "Label adjacent sibling input"
xpath do |locator|
XPath.descendant(:label)[XPath.string.n.is(locator)].next_sibling(:input)
end
end
which could then be used as
element :some_field, :sibling_input, 'label text'
I'm trying to create an image_tag and specify a data- attribute that does not have any value set to it. I'm trying to add data-tooltip, for use with Foundation 5 tooltips. It seems that if any value is actually set to this, Foundation uses the same tooltip text every time and ignores the title attribute of that element (so every tooltip will say whatever the first one you hovered on was... which seems buggy in and of itself on Foundation's part also)
This is what I need to generate:
<img src="[whatever]" title="My Tooltip" data-tooltip />
This will not work for me:
<img src="[whatever]" title="My Tooltip" data-tooltip="[insert anything here]" />
I have tried a number of different combinations, and read documentation, but it seems no matter what I put as the value, it ends up generating it like data-tooltip="null", or true, or false, or any string I pass.
image_tag(my_image, class: 'has-tip', title: "My Title Here", data: { tooltip: true })
Try to pass in empty string as follows:
image_tag(my_image, class: 'has-tip', title: "My Title Here", data: { tooltip: "" })
In Rails 4.1.4 using above tip :"data-tooltip" => '' renders data-tooltip without value.
For an attribute with no value like multiple <input multiple type="file">, you can override the attribute default name, by uppercasing and setting an empty string. For example input_html: { Multiple: '' } But this is a hack.
In rails 5, I was trying to add itemscope attribute with no value in the following link tag scenario:
<%= link_to example_path(#example) do %>
<span>
<%= #example.name %>
</span>
<% end %>
I needed the resulting html a tag to show the itemscope attribute without any value like so:
<a itemscope href="example/path">
<span>
some text
</span>
</a>
Notice the itemscope has no ="" or itemscope="itemscope".
I tried solutions from SO and other places and the only thing that worked for me was adding the following to the link_to tag: " itemscope" => ''. Notice the space between the first double quote and the word itemscope.
This seems to generate the desired outcome and also validated as schema.org tag on google (that is what i used the tag for).
