I would like to loop over all the variables in a single partial, but I can't find away to automate this.
The example:
I have a partial named _colors.scss, it only contains colour variables.
$facebook: #305897;
$twitter: #31aae1;
$google: #da4936;
$pinterest: #c9151a;
These are already used across the site so I can't reformat them as a list.
I would like to do something like, foreach var in _colors return mixin.
But I can't find away to access them without calling each individually...
I am sure I am missing something obvious, and would appreciate someone pointing it out :)
There is no shortcut for this. You'll have to create a list out of them yourself.
$facebook: #305897;
$twitter: #31aae1;
$google: #da4936;
$pinterest: #c9151a;
$social: $facebook, $twitter, $google, $pinterest;

I have a dropdown of vehicle makes that I want my users to start selecting as they type. First character typed should find the first character in the makes. The problem is that it searches anywhere in the make for a character and does not start at the first character like my users would like. For example... if you type an "r" you get: Alfa Romeo, Aston Martin, Chevrolet, Chrysler, etc... well before you get a Renault.
I create my list from the database. My haml looks like this:
.field-row
= render partial:'/makes/make_select', locals:{id:'make_id'}
That calls this _make_select.html.haml
= collection_select :vehicle, id, Make.all.order(:name), :id, :name, {prompt:true}, {title:'Select Make', class:'make-select', 'data-allow-empty' => 'no'}
I cant seem to find any docs on Ruby that shows me the valid options for collection_select. Maybe there is an option that allows this?
I have read that I might need to use jQuery to accomplish this. Was just trying to figure out if there might be an easier way with just a simple option in the haml.
Let me know if there is anything else you would like to see.
thanks!
You could add logic to your controller and to check using a SQL query, something like this, depends on the database you're using.
#makes = Make.where('name LIKE ?', "#{params[character]}%")
Check out the MySql docs on pattern matching
https://dev.mysql.com/doc/refman/8.0/en/pattern-matching.html
You should not add your Model query inside a view, should add it.
In your above case, I suggest you use https://github.com/argerim/select2-rails it very powerful and already have what you need.

I have:
//*[text()='Reception']//preceding::th[contains(#id, 'ep')]//following::I
But it only registers following.
The default firepath selector is: .//*[#id='mw-content-text']/div/table[5]/tbody/tr/td[1]/I but this kind of selector is known to break quite frequently. Just wondering if there is a better way of doing this and I thought this might be a way.
Thanks!

- You can see that it's getting stuff under the table which is not what I want :S
Try to use below XPath to match required elements:
//th[contains(#id, 'ep')]/following::I[./following::*[text()='Reception']]
This looks more simple
//tr[contains(#class, 'vevent')]//i
Don't overcomplicate things. You need I tag inside each row. So just find row locator tr[contains(#class, 'vevent')] and get it's I
Another good approach in case you want to check that inside of parent element is located some special element, but you want to find some 3rd element is to use such style: //element[./specific]//child , so in your case:
//tr[contains(#class, 'vevent')][./th[contains(#id,'ep')]]//i
so it's I tag inside row that contains #id,'ep' in header
I am currently teaching myself game programming, and I've started nice and easy with pygame. I went through a tutorial that showed me how to build a simple game, and now that I am finished with it, I am in the process of trying to reorganize the code in a manner that makes sense to me, and also to edit it and add to it.
Part of what I tried to change is that instead of loading one '.png' file for a character, I load a list of them that will be iterated through in a 'move()' function I designed to make the characters look like they are moving. However I keep running into an error and I don't know why. Near the beginning of my code (all I've done is imported necessary modules and initialized pygame and some necessary variables) I tried to do the following code:
badguyimgs = ['badguy.png', 'badguy2.png', 'badguy3.png', 'badguy4.png']
for img in badguyimgs:
badguyimgs.append(pygame.image.load("resources/images/" + img))
badguyimgs.remove(img)
I keep getting the following error:
TypeError: cannot concatenate 'str' and 'pygame.Surface' objects
So far I have tried to initialize a new variable (resource = "resources/images/" + img) and place that at the beginning of the "for" loop and then insert that into the pygame.image.load(). I've also tried using os.path.join("resource/images/" + img). I've tried using the full path name ("c:\\Users\\ . . . \\resources\\images\\" +img). But any time I try to concatenate the pathname with the file name in the list, I get the above error code. I tried looking in the pygame documentation, but didn't see anything that helped in this situation. I've tried googling the error, but get nothing in reference to this. (a lot of issues with people tring to concatenate int types to strings though. . . ) I would appreciate any help anyone could give in pointing out why I am experiencing this, and what could fix it. Thanks.
It looks like what you're doing is appending the pygame.surface object (that you loaded from a png file) to the list while you're iterating through it. You are loading the images successfully. However after your function adds the first image and removes the string, your list looks like this:
badguyimgs = ['badguy2.png', 'badguy3.png', 'badguy4.png', pygame.image]
You are still iterating through the list, so your function starts trying to concatenate the string and the pygame.surface object. I would recommend creating an empty list, and add your loaded images to that list without adding or removing anything from the original. Hope this helped!
Here's an example to go with PlatypusVenom's explanation:
file_names = ['badguy.png', 'badguy2.png', 'badguy3.png', 'badguy4.png']
images = []
for file_name in file_names:
images.append(pygame.image.load("resources/images/" + file_name))
Now the pygame.Surface objects are in images, and the variable names for the lists are less confusing. Another option is to use a list comprehension:
images = [pygame.image.load("resources/images/" + file_name) for file_name in \
("badguy.png", "badguy2.png", "badguy3.png", "badguy4.png")]
This is similar to what you were going for in the code posted. The list of strings will be removed from memory, leaving only pygame.Surface objects in the images list.
I have Адреса магазинов on page and want to store text, then click on this link and verify that the page where am I going to contains this text in headers. So I tried to find element by xpath, and selenium.getText get the right result, but selenium.click goes to another link. Where have I made a mistake? Thanks in advance!
String m_1 = selenium.getText("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.click("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.getText("css=h3").contains(m_1));
page:http://www.svyaznoy.ru/map/
Resume:
using xpath=//descendant::a[#href='/address_shops/'][2] or css=div.deff_one_column a[href='/address_shops/'] get right results
using xpath=//a[#href='/address_shops/'] - Element is not currently visible
xpath=//a[#href='/address_shops/'][2] - Element not found
There is a missing slash at the beginning of the expression. I am kind of surprised this got through at all - the first slash means "begin at root node".
Also, it is better to select the <a> element instead of the <h>. Sometimes it works, sometimes is misclicks, sometimes the click doesn't do anything at all. Try to be as concrete as you can be.
Try this one.
String m1 = selenium.getText("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.click("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.waitForPageToLoad("30000");
// your variable is named m1, but m_1 was used here
assertTrue(selenium.getText("css=h3").contains(m1));
By the way, there are even better XPath expressions you could use. See the documentation, it really is helpful. Just an example, this would work, too, and is much easier to write and read:
String m1 = selenium.getText("xpath=//a[#href='/address_shops/']");
selenium.click("xpath=//a[#href='/address_shops/']");
Sorry, didn't notice page link. Css for second link can be something like that css=div.deff_one_column a[href='/address_shops/']
I want to use XPath code in an InfoPath form to sum the data in field12 when field11 is equal to IT. I tried using the following code, but it doesn't work.
number(sum(/descendant-or-self::node()/my:group12[my:field11 = "IT;"]/my:field12))
I suspect this has to do with the multilayering of groups, as shown below. Does anyone know the code that would allow me to get to the data in group12? Thanks in advance for your help.
myfields>group9>group10>group11>group12>field11 field12
Genipro
Looks like:
number(sum(/descendant-or-self::my:group12[my:field11 = 'IT;']/my:field12))
could be right.
decendant-or-self should not be necissary in this case (unless you need the expression to work even if group12 is moved).
This should work fine:
sum(/my:myfields/my:group9/my:group10/my:group11/my:group12[contains(my:field11,'IT')]/my:field12)
It doesn't matter if any of the other groups are repeating either. All group12's will be checked.
