QUESTION
I have to develop a reservation system for a hotel. You first have to create a user and than you can make a reservation. There is an option to edit the registered users but that is the part where I'm stuck. I follow a very good tutorial but at the moment I can't figure out my error from his video or the internet or documentation..
I've used the post method to insert new data inside my database but to edit the data and update it, I have to use the put method. But it gives an error "Too few arguments in my function .. 1 passed in and 2 expected".
I am aware I have to cache the routes at every change!!
This is my controller:

Route::get('/clients/{id}/edit', [GuestsController::class, 'edit']);
QUESTION
The code below creates Perl/Tk
buttons filled with each event's details from the hash %events
. Is there a way to format the text inside the buttons so that it appears in aligned columns in the manner printf prints it out on line 16.
ANSWER
Answered 2022-Mar-05 at 20:16To align the columns, set font of each button to "Courier" (or another monospaced font). There are at least two ways to do this:
- when creating the button
- assign the button to a variable and then call
configure
on it.
QUESTION
What does this code do with the list of functions?
...ANSWER
Answered 2022-Jan-23 at 16:47The original functions are curried twice with an argument value: once with store
, and the second time with a callback function dispatch
, which through reduceRight
is a function that refers to the next curried function in the array.
So f*
should be functions that take two arguments: the object that plays a role (for anything you want), and the callback function to be called next. The exception to this rule is the last function: it doesn't get a second argument.
Here is an example for those functions:
QUESTION
I'm trying to get all the links in the div "Notes et références" on this page:
https://fr.wikipedia.org/wiki/Barack_Obama
but it seems that I don't have the right selector. I tried this but it didn't work:
...ANSWER
Answered 2021-Dec-04 at 23:49Just because the element is scrollable doesn't mean you actually need to scroll to get the data. It's generally only for JS-driven, dynamic feeds that you need to mess with scrolling.
In this case, the data is available statically, so unless you're using Puppeteer for some other reason, you could just do this with a simpler and probably faster Axios/Cheerio combo.
Even better is to use Wikipedia's API rather than scraping the data. If you do scrape, please respect their limits for robots.
Continuing on with Puppeteer, Wikipedia has odd page structures that don't nest sections. After selecting #Notes_et_références
, you can pop up to the parent
.reference-cadre
element (I hardcoded this relationship, but you could make it more dynamic with a loop if being a bit more future-proof is a goal).
QUESTION
I have a fairly simple C# WPF application using .NET 5. Basically it sits in the background and times specific events for the end user. The events are built from a xml file that is generated externally.
The application consists of 2 windows, one hidden that does all the thinking. If it detects that an event is due it raises a toast message which when clicked on opens the other window to show the event details to the user. All works fine and runs as expected except after a windows sleep/suspend and resume. We obviously don't want the events to add up upon sleep/suspend and so we close the hidden window and upon resume open it again. No problems there but once the system is resumed and an event is raised the visible window refuses to show. If the visible window is open when sleep/suspend happens then upon resume the whole window is frozen and refuses to respond (only way to close the window is kill the application and restart)
The APP code is as follows :-
...ANSWER
Answered 2021-Oct-22 at 11:53After much work and going through the code section by section commenting it out to see if it made a difference I have found the issue.
Buried deep inside the the code for the hidden window (4 calls to functions down the line) I found that the EventHandler() was also raising a listener for
QUESTION
I have a "flashing" script being loaded into a Uboot, on an iMX6, from a host PC via sdp. The script has been run through mkimage
, so it has an image header. Here's the mkimage command:
ANSWER
Answered 2021-Sep-15 at 01:55What am I doing wrong?
U-Boot almost always assumes hexadecimal values for command arguments, so using the 0x...
prefix is actually superfluous. AFAIK there is no way to input decimal values.
QUESTION
If I run the toy script below as shown:
...ANSWER
Answered 2021-Sep-13 at 16:49It seems that calling aqt._run(*args, exec=False)
returns a QApplication
object - but without starting its event-loop. To manually process pending events, you could therefore try calling app.processEvents()
.
From the comments, it appears the exact solution is as follows:
QUESTION
In continuation to my previous question C# Confluent.Kafka SetValueDeserializer object deserialization, I have tried creating my custom deserializer to deserialize protobuf message but getting this error:
...ANSWER
Answered 2021-Sep-08 at 09:50As I noted yesterday, you appear to have used the Google .proto processing tools (protoc
), but are using protobuf-net; if you want to use protobuf-net, similar command-line/IDE/build/etc tools exist that are compatible with the protobuf-net library, or you can use https://protogen.marcgravell.com/ for ad-hoc usage (to avoid having to install anything). Alternatively: continue using the Google schema tools, but use the Google library. Basically: they need to match.
The only minor gotcha here is that protobuf-net does not currently have explicit inbuilt support for DoubleValue
; for reference: this can be considered as simply:
QUESTION
I will write my question as is;
There are two indices under your cluster; earthquakes and magnitude_type
lets say earthquakes index has bunch of fields and a "MagnitudeType" magnitude_type index has "MagnitudeType" and "MagnitudeTypeDesc"
you want to create a new index named my_index; my_index should have all the documents from earthquakes, we will add "MagnitudeTypeDesc" field to my_index and then populate it according to magnitude_type index where "MagnitudeType" field matches.
How can one do this?
Thanks
UPDATE!!!!
I used Val's suggestion as below,
...ANSWER
Answered 2021-Sep-03 at 14:46You did everything right by mimicking what this thread advocates for, i.e. using an enrich
processor to join data from the magnitude_type
index into the new_index
.
Now you simply need to flatten down the matched magnitude object using another processor called rename
and also remove
the temporary result object from the enrich processor, like this:
QUESTION
I have a perl/tk script that uses a canvas with text. A while back the font of the text changed alone: no more sans-serif! Probably some update/upgrade messed up my fonts, but they should be there somewhere. I only found this problem in perl/tk scripts.
I downloaded a small perl script that shows the installed fonts, and indeed no sans-serif appears. In fact, only 30 or so fonts appear. The command xlsfonts
gives me more than 1600 fonts, yet xfontsel
only shows these 30 font families.
How did the sans font disappear, and how do I restore/install back missing fonts?
This is the script I used to see the fonts:
...ANSWER
Answered 2021-Jul-09 at 15:39In some of the last updates this has been fixed. Sans fonts are back.
