I have a json field that is either absent or is set to true. But in my document I want it to show up as "Yes" or "No". I tried the following conditional expression ():
{% conditional-section expr(`my_field` = true) %}Yes{% end-section %}{% conditional-section expr(`my_field`!= true) %}No{% end-section %}
But when I call the Adobe Document Generation API, the PDF I get still has these template tags. For some reason it is not being detected. How can I achieve this?
I know I asked a question above in the comment, but I think I can take a stab at answering this now. So right now there is not a way to say "if a value is NOT present or present and equal to yes." There's a few ways you can handle this, but I think the easiest would be to change your data. To be clear, I don't mean change your database or anything, but keep in mind that before you call our API, you can massage the data a bit. So if the absence of my_field means yes, I'd do something like this (JavaScript):
if(!mydata.my_field) {
mydata.my_field = 'yes';
}
You could then do something like this:
{% conditional-section expr(my_field = "yes") %}
Yes
{% end-section %}
{% conditional-section expr(my_field = "no") %}
No
{% end-section %}
However, this will not be on the same line. As I said, this is a known issue. If you need it as such, again, I'd use the idea of massaging your data first. You could do something like this (again, JavaScript, but could be done in any language):
if(!mydata.my_field) {
mydata.my_field = 'yes';
}
if(mydata.my_field === 'yes') mydata.my_field_value = 'Yes';
else mydata.my_field_value = 'No';
All I did there was, based on the value of my_field, set another variable. In your Word template you can then simplify even more by just using {{my_field_value}}
With Document Generation being so flexible, you've got multiple different ways of solving a problem.
I have found this works for me:
{{my_field ? "Yes" : "No"}}

I've defined
\usepackage{zref-savepos}
\newcommand*{\curypos}[1]{%
\zsaveposy{#1}%
\zposy{#1}sp = %
\the\dimexpr\zposy{#1}sp\relax%
}
and that seems to work fine. Saying \curypos{some_label} reports the y position on the page, just as expected.
Now do
\newenvironment{mytest}[2]
{\write\myfile{\curypos{#1} #2}%
}
{% Do nothing to close out the environment.
}
\begin{mytest}{first}{second}
pointless blather
\end{mytest}
The contents of \myfile do not show the y-position on the page. Instead they show
\zsaveposy {first}0sp = 0.0pt second
For some reason, first is not passing through as an argument to \curypos.
I'm guessing that this is some form of fragility, so I tried using \protect in various places and declaring \curypos with \DeclareRobustCommand, but none of them work.
This isn't a complete answer, but I think the problem is due to the fact that the call to \zsaveposy is made from within a \write. My guess is that these write operations are treated as though they take place at the top (or bottom?) of the page so that the position is always (0,0). Breaking up the definition of the environment command as follows works.
\newenvironment{intfig}[2]
{\zsaveposy{#1}%
\write\myfile{\the\dimexpr\zposy{#1} #2 }%
}
{% nothing
}
Just new in Prestashop (1.6.0.6), I've a problem with my product page in admin. All translatable-field are to display:none (I inspect the code with chrome).
So when I want to create a new product I can't because the name field is required.
I thought that it was simple to find the .js whose do that but it isn't.
If somebody could help me, I would be happy.
Thank you for your help
Hi,
I make some searches and see that the function hideOtherLanguage(id) hide and show translatable-field element.
function hideOtherLanguage(id)
{
console.log(id_language);
$('.translatable-field').hide();
$('.lang-' + id).show();
var id_old_language = id_language;
id_language = id;
if (id_old_language != id)
changeEmployeeLanguage();
updateCurrentText();
}
When I set the Id to 1 (default language), it works. It seems that when I load the page, the function is called twice and the last calling, the id value is undefined. So the show() function will not work.
If somebody could help me. Thank you.
In my console, I see only one error
undefined is not a function.
under index.php / Line 1002
...
$("#product_form").validate({
...
But I find the form.tpl template and set this lines in comment but nothing change.
EDIT: According to comment on this link http://forge.prestashop.com/browse/PSCFV-2928 this can possibly be caused by corrupted installation file(s) - so when on clean install - try to re-download and reinstall...
...otherwise:
I got into a similar problem - in module admin page, when creating configuration form using PrestaShop's HelperForm. I will provide most probable cases and their possible solutions.
The solution for HelperForm was tested on PS 1.6.0.14
Generally there are 2 cases when this will happen.
First, you have to check what html you recieve.
=> Display source code - NOT in developer tools/firebug/etc...!
=> I really mean the pure recieved (JavaScript untouched) html.
Check if your translatable-fields have already the inline style "display: none":
Case 1 - fields already have inline style(s) for "display: none"
This means the template/html was already prepared this way - most probably in some TPL file I saw codes similar to these:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $id_lang_default}style="display:none"{/if}>
Or particularly in HelperForm template:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $defaultFormLanguage}style="display:none"{/if}>
Case 1 is the most easy to solve, you just have to find, where to set this default language.
Solutions
HelperForm
Look where you've (or someone else) prepared the HelperForm object - something like:
$formHelper = new HelperForm();
...
Somewhere there will be something like $formHelper->default_form_language = ...;
My wrong first solution was to get default form language from context - which might not be set:
$this->context->controller->default_form_language; //THIS IS WRONG!
The correct way is to get the default language from configuration - something like:
$default_lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
$formHelper->default_form_language = $default_lang->id;
...this particularly solved my problem...
Other form-creations
If there is something else than HelperForm used for form creations, the problem is still very similar.
You have to find where in files(probably tpls) is a condition for printing display:none for your case - then find where is the check-against-variable set and set it correctly yourself.
Case 2 - fields don't have inline style(s) for "display: none"
This means it is done after loading HTML by JavaScript. There are two options:
There is a call for hideOtherLanguage(), but there is wrongly set input language - that means no language will be displayed and all hidden.Solution for this one can be often solved by solving Case 1 (see above). In addition there can be programming error in not setting the after-used language id variable at all... then you would have to set it yourself (assign in JavaScript).
Some script calls some sort of .hide() on .translatable-field - you will have to search for it the hard way and remove/comment it out.
PS: Of course you can set the language to whatever you want, it is just common to set it to default language, because it is the most easier and the most clear way how to set it.
i am learning asp.net mvc just going through online tutorial
1) just see <span>#model.Message</span> and #Html.Raw(model.Message)
suppose if "Hello Word" is stored in Message then "Hello Word" should display if i write statement like
<span>#model.Message</span> but i just could not understand what is the special purpose about #Html.Raw(model.Message).
what #Html.Raw() will render ?
please discuss with few more example to understand the difference well.
2) just see the below two snippet
#if (foo) {
<text>Plain Text</text>
}
#if (foo) {
#:Plain Text is #bar
}
in which version of html the tag called was introduce. is it equivalent to or what ? what is the purpose of
this tag ?
just tell me about this #:Plain Text is #bar
what is the special meaning of #: ?
if our intention is to mixing text with expression then can't we write like Plain Text is #bar
3) <span>ISBN#(isbnNumber)</span>
what it will print ? if 2000 is stored in isbnNumber variable then it may print <span>ISBN2000</span>. am i right ?
so tell me what is the special meaning of #(variable-name) why bracket along with # symbol ?
4) just see
<span>In Razor, you use the
##foo to display the value
of foo</span>
if foo has value called god then what this ##foo will print ?
5 ) see this and guide me about few more syntax given below point wise
a) #(MyClass.MyMethod<AType>())
b)
#{
Func<dynamic, object> b =
#<strong>#item</strong>;
}
#b("Bold this")
c) <div class="#className foo bar"></div>
6) see this
#functions
{
string SayWithFunction(string message)
{
return message;
}
}
#helper SayWithHelper(string message)
{
Text: #message
}
#SayWithFunction("Hello, world!")
#SayWithHelper("Hello, world!")
what they are trying to declare ? function ?
what kind of syntax it is ?
it seems that two function has been declare in two different way ? please explain this points with more sample. thanks
Few More question
7)
#{
Func<dynamic, object> b = #<strong>#item</strong>;
}
<span>This sentence is #b("In Bold").</span>
what the meaning of above line ? is it anonymous delegate?
when some one will call #b("In Bold") then what will happen ?
8)
#{
var items = new[] { "one", "two", "three" };
}
<ul>
#items.List(#<li>#item</li>)
</ul>
tell me something about List() function and from where the item variable come ?
9)
#{
var comics = new[] {
new ComicBook {Title = "Groo", Publisher = "Dark Horse Comics"},
new ComicBook {Title = "Spiderman", Publisher = "Marvel"}
};
}
<table>
#comics.List(
#<tr>
<td>#item.Title</td>
<td>#item.Publisher</td>
</tr>)
</table>
please explain briefly the above code. thanks
1) Any kind of #Variable output makes MVC automatically encode the value. That is to say if foo = "Joe & Dave", then #foo becomes Joe & Dave automatically. To escape this behavior you have #Html.Raw.
2) <text></text> is there to help you when the parser is having trouble. You have to keep in mind Razor goes in and out of HTML/Code using the semantics of the languages. that is to say, it knows it's in HTML using the XML parser, and when it's in C#/VB by its syntax (like braces or Then..End respectively). When you want to stray from this format, you can use <text>. e.g.
<ul>
<li>
#foreach (var item in items) {
#item.Description
<text></li><li></text>
}
</li>
</ul>
Here you're messing with the parser because it no longer conforms to "standard" HTML blocks. The </li> would through razor for a loop, but because it's wrapped in <text></text> it has a more definitive way of knowing where code ends and HTML begins.
3) Yes, the parenthesis are there to help give the parser an explicit definition of what should be executed. Razor makes its best attempt to understand what you're trying to output, but sometimes it's off. The parenthesis solve this. e.g.
#Foo.bar
If you only had #Foo defined as a string, Razor would inevitably try to look for a bar property because it follows C#'s naming convention (this would be a very valid notation in C#, but not our intent). So, to avoid it from continuing on we can use parenthesis:
#(Foo).bar
A notable exception to this is when there is a single trailing period. e.g.
Hello, #name.
The Razor parser realizes nothing valid (in terms of the language) follows, so it just outputs name and a period thereafter.
4) ## is the escape method for razor when you need to actually print #. So, in your example, you'd see #foo on the page in plain text. This is useful when outputting email addresses directly on the page, e.g.
bchristie##contoso.com
Now razor won't look for a contoso.com variable.
5) You're seeing various shortcuts and usages of how you bounce between valid C# code and HTML. Remember that you can go between, and the HTML you're seeing is really just a compiled IHtmlString that is finally output to the buffer.
1.
By default, Razor automatically html-encodes your output values (<div> becomes <div>). #Html.Raw should be used when you explicitly want to output the value as-is without any encoding (very common for outputting JSON strings in the middle of a <script>).
2.
The purpose of <text> and #: is to escape the regular Razor syntax flow and output literal text values. for example:
// i just want to print "Haz It" if some condition is true
#if (Model.HasSomething) { Haz It } // syntax error
#if (Model.HasSomething) { <text>Haz It</text> } // just fine
As of #:, it begins a text literal until the next line-feed (enter), so:
#if (Model.HasSomething) { #:Haz It } // syntax error, no closing '}' encountered
// just fine
#if (Model.HasSomething)
{
#:Haz It
}
3.
By default, if your # is inside a quote/double-quotes (<tr id="row#item.Id"), Razor interprets it as a literal and will not try to parse it as expression (for obvious reasons), but sometimes you do want it to, then you simply write <tr id="row#(item.Id").
4.
The purpose of ## is simply to escape '#'. when you want to output '#' and don't want Razor to interpret is as an expression. then in your case ##foo would print '#foo'.
5.
a. #(MyClass.MyMethod<AType>()) would simply output the return value of the method (using ToString() if necessary).
b. Yes, Razor does let you define some kind of inline functions, but usually you better use Html Helpers / Functions / DisplayTemplates (as follows).
c. See above.
6.
As of Razor Helpers, see http://weblogs.asp.net/scottgu/archive/2011/05/12/asp-net-mvc-3-and-the-helper-syntax-within-razor.aspx
I have another probably basic problem. happy if u can help.
there is a request parameter 'action'. if I write :
<label><s:property value="%{#parameters.action}"/></label>
the value appears (it is 1)
So itry to test now :
<s:if test="%{#parameters.action == '1'}">YES 1</s:if><s:else>NOT 1</s:else>
NOT 1 appears.
I have tries all the syntaxes I found on the net for the test. Nothing changes, NOT 1 still displays
Thank you
This is because:
the value of %{#parameters.action} is an array, not a single value, and
the value will be type-converted to a number (not sure why; need to look in to that)
The correct expression would be:
<s:if test="%{#parameters.action[0] == 1}">YES 1</s:if><s:else>NOT 1</s:else>
The correct expression would be:
<s:if test="#parameters.action[0] == 1">YES 1</s:if><s:else>NOT 1</s:else>
The request parameters is a map of [Strinf, String[]], So you have to access it like above
I want to remove all images from a HTML page (actually tinymce user input) which do not meet certain criteria (class = "int" or class = "ext") and I'm struggeling with the correct approach. That's what I'm doing so far:
hbody = Hpricot(input)
#internal_images = hbody.search("//img[#class='int']")
#external_images = hbody.search("//img[#class='ext']")
But I don't know how to find images where the class has the wrong value (not "int" or "ext").
I also have to loop over the elements to check other attributes which are not standard html (I use them for setting internal values like the DB id, which I set in the attribute dbsrc). Can I access these attributes too and is there a way to remove certain elements (which are in the hpricot search result) when they don't meet my criteria?
Thanks for your help!
>> doc = Hpricot.parse('<html><img src="foo" class="int" /><img src="bar" bar="42" /><img src="foobar" class="int"></html>')
=> #<Hpricot::Doc {elem <html> {emptyelem <img class="int" src="foo">} {emptyelem <img src="bar" bar="42">} {emptyelem <img class="int" src="foobar">} </html>}>
>> doc.search("img")[1][:bar]
=> "42"
>> doc.search("img") - doc.search("img.int")
=> [{emptyelem img src"bar" bar"42"}]
Once you have results from search you can use normal array operations. nonstandard attributes are accessible through [].
Check out the not CSS selector.
(hbody."img:not(.int)")
(hbody."img:not(.ext)")
Unfortunately, it doesn't seem you can concat not expressions. You might want to fetch all img nodes and remove those where the .css selector doesn't include neither .int nor .ext.
Additionally, you could use the difference operator to calculate which elements are not part of both collections.
Use the .remove method to remove nodes or elements: Hpricot Altering documentation.
