I am currently trying to hide specific elements, if the creditUser in my app has credit less than the costs of a specific dish. (It's kind of a dish ordering system, just for training purposes) And I cannot figure out how to set up the thymeleaf condition, to make it work...
I've tried all kinds of solutions, but all I can find on the internet is something like this: th:if="*{ score < 20 and score >= 0}"
my current version looks like this:
<td ><a th:if="${creditUser.credit} > ${dish.small}" class="btn btn-success" th:href="#{/order/orderDish/(creditUserId=${creditUser.id},dishId=${dish.dishId},delId=${dish.delId},dishName=${dish.name},price=${dish.small})}" th:text="${dish.small}">Bestellen</a></td>
Now I don't get any error messages, but the element is also not showing up. Any suggestions on how to compare a value in thymeleaf to another value? (The creditUser is passed it is just not shown in the code part and the solution works with fixed values like creditUser.credit > 1)
Everything should be inside the same braces:
th:if="${creditUser.credit > dish.small}"

So there is a page that I want to perform some action on with puppeteer. The problem is that there is a text area in which I want to type in something however the id of it is :
id="pin-draft-title-13a10e18-5a1e-49b9-893c-c5e028dc63e1"
As you might have guess for some reason only pin-draft-title remains the same but the whole number part changes for every refresh so puppeteer can't find it. I tried deleting the id and copying the selector itself the whoe #_Root div>div etc but that seems to be changing after sometime as well. So the main question is is there any way i can just select it using the pin-draft-title part and no matter what numbers follow it still selects it ?
You can use [id^=pin-draft-title-]
In case of javascript, if you want to select all the elements whos ID starts with a specified string or pattern, in your case "pin-draft-title", then consider using the following syntax.
document.querySelectorAll('[id^="pin-draft-title"]');
I have that code:
(?:19|20)[0-9]{2}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))
Checks that
1) the year is numeric and starts with 19 or 20,
2) the month is numeric and between 01-12, and
3) the day is numeric between 01-29, or
b) 30 if the month value is anything other than 02, or
c) 31 if the month value is one of 01,03,05,07,08,10, or 12
It's from page http://html5pattern.com/Dates
I tried to move some part of code, but then this code doesnt work... Even I tried to find some instructions how can I do it. But I can't handle with it...
How can I get a result like with above code but in format:
DD.MM.YYYY
Also is there any possibility to add the dots in field that user can only input the numbers without dots?
(I mean that the dots will be there every time)
Thank you for help.
Sorry for my English.
I think this is something that you are looking for:
(?:(?:0[1-9]|1[0-9]|2[0-9])\.(?:0[1-9]|1[0-2])|(?:30)\.(?:(?!02)(?:0[1-9]|1[0-2]))|(?:31)\.(?:0[13578]|1[02]))\.(?:19|20)[0-9]{2}
Also tried some possible test cases and worked fine:
You can use an input mask plugin for some of what you are asking for instead I suppose.
One popular one that comes to my mind is Robin Herbots: https://github.com/RobinHerbots/Inputmask
You can find demos off his page here: https://robinherbots.github.io/Inputmask/index.html
Once you implement the plugin into your page, then it's just a matter of establishing the right input tags and jquery for them. For example:
Your phone number script would then be something along the lines of:
<script type="text/javascript">
$("#Phone").inputmask({mask: "999.999.9999"});
</script>
You should look up the documentation for it.
I have the object TABLE_LIST which is a list that has tables (I can't provide the contents for privacy policies, sorry).
I first created the object TABLE_LIST (It is a list of data.frames 2x12)
TABLE_LIST=lapply(1:4, function(x) data.frame(rbind(total.ratio4[[x]][-(1)], total.ratio2[[x]][-(1)]), row.names=row))
The following code gives me red and green font colors based on the value on the cell, and it works like a charm:
formattable(TABLE_LIST[[1]], list(area(,-(c(5,10)))~formatter("span", style=x~style(color=ifelse(x>1,"red","green"))),area(,(c(5,10)))~formatter("span", style=x~style(color=ifelse(x>1,"green","red")))))
However, I need COLOR AND comma separated numbers. My failed attempt is:
formattable(TABLE_LIST[[1]], list(area(,-(c(5,10)))~formatter("span", style=x~style(color=ifelse(x>1,"red","green"))),area(,(c(5,10)))~formatter("span", style=x~style(color=ifelse(x>1,"green","red"),digits(x,2))),
area(1:2,1:10)~formatter("span",x~ style(digits(x,2)))))
This code works well, but erases the formatting of the color. I do not know what else to do.
I have to mention I cannot change the original data.frame without messing everything up. So I gotta make the changes on table_list or formattable. Thank you.
I think I solved it. So I will share this small knowledge to people who may have the same problems as me:
formattable(TABLE_LIST[[1]],
list(
area(,-(c(5,10)))~formatter("span",
style=x~style(color=ifelse(x>1,"red","green")),
x~style(digits(x,4))),
area(,(c(5,10)))~formatter("span",
style=x~style(color=ifelse(x>1,"green","red")),
x~style(digits(x,4)))))
Basically, inside the same formatter, on the level of style, add a comma and x~style.
I am trying to extract this website using VBA
This is the HTML I want to Target
<div class="claim"> <div num="1" id="US-6627754-B2-CLM-00001" class="claim">
to get data for various numbers, only constant things is
<div class ="claims" and class ="claim"
rest of the html is dynamic.
following code just works fine for first element.
oHtml.getElementsByClassName("claim").Item.innerHTML
for this case
oHtml.getElementsByTagName("div")(90).innerHTML
also gives desired result.
I don't have basic knowledge of HTML or VBA.
I know that this is not correct as it gives duplicate entry one for div class="claim" and other for class="claim" and div(90) is not always constant.
How to just target
<div class = "claim"
Tried oHtml.getElementsByTagName("div")(90).getElementsByClassName("claim").Item.innerHTML
but did not gave results. For this specific website it is at div 90. again its not constant.
Have you tried finding ir by using the id as this is uniqe and can only be used once so you won't get duplicates ! On my phone atm so can't give eg if you need I will when on my computer! I'm studying both html and vba not a pro but I think I know what i'm doing!
Im having a hard time deciding what is the best way to pull pictures from a separate table, for a certain item.
In django, I have two tables:
class item(models.Model):
title..
descr..
class item_pic(models.Model):
item=models.ForeignKey(item)
pic=models.ImageField...
Im displaying the item.title and item.descr in a div, and in the same div I want to pull the pictures.
So far I've tried creating a template filter like item|getPics which returns a list of the pics for that item.
{% for pic in item|getPics %} <img src="/uploads/{{pic.pic}}"> {%endfor%}
In the end I got rid of this since it was firing too many sql queries
Right now I finished pulling the pictures through ajax, the only downside here is that the images take some time to appear. And I assume is the same number of sql queries (only that django debug toolbar doesnt see them since they are fired up in the background).
How would you approach this? Thanks for any tips!
You should use select_related() (docs) to get the image objects together with the items.
It would look like this:
item = item.objects.select_related().get(...)
This means you won't get additional database queries when you're retrieving the item_pics.
As a final note, it's better to capitalize the names of classes as this is convention in Python/Django.
