QUESTION
I want to create a function where I can run dynamic linq queries.
Instead of creating a separate linq query for every search, I want to create one dynamic function, where I can pass the column name, I want to search.
So far, my dynamic linq query returns the string value in the search parameter, and I cannot reach the ID in the list
...ANSWER
Answered 2021-Jan-23 at 00:53var separaList = authorList.Select(l => column).ToList();
this code is not good, because you are selecting what have you send to the function, if you are sending Name
will select six times Name
or if you are sending Other
will select six times Other
.
If i undertand correctly, you can achieve this by using Reflection, so the function SearchColumn
will be like :

I am new in C world. I understand C code needs to be build which means compiling the code and producing exectuable. But here on this page I read this line :
A developer typically builds applications against the IDF
I know what IDF stands for. What i dont understand is meaning of this line. What is the meaning of building C application against something?
...ANSWER
Answered 2020-Dec-13 at 19:49Most programs do not stand on their own. They use routines, data, and definitions from other software. Such other software might be organized as part of an operating system, as a software library or framework or other packaging.
When a program is built, pieces of such other software are used in building it: It may use “header” files from the other software, incorporate routines from static libraries, link to routines in dynamic libraries, and use an executable file format required by the operating system. This is called “building against” the other software. I would, however, classify that as an informal term, not a technical definition of how the linking proceeds.

I have an almost working sign up form with Devise. Whilst it seems to work, it's not saving the fields in my Custaddress

Devise's create

method that you are overriding. the problem is that you overrid it for the new
action but didn't take into account the create
action.
So, you are doing this:

My idea is to make each element within div
s that have the .main_content
class, to have a width equal to the width of the text inside it. How do I this?
As you can see, the width of each one (span
, h2,
p
and h6
) is the same as the .main_content
div
. The red border demonstrates this.
So, how do I make the width of each div fit the text within those divs? (With only CSS)
...ANSWER
Answered 2020-May-16 at 17:16Just 1 CSS function: width: fit-content
Note here: It doesnt work in IE.

Use inbound and outbound channel adapters
QUESTION

QUESTION
I currently have a Spring Integration application which is utilizing a number of TCP inbound and outbound adapter combinations for message handling. All of these adapter combinations utilize the same single MessageEndpoint for request processing and the same single MessagingGateway
for response sending.
The MessageEndpoint’s final output channel is a DirectChannel
that is also the DefaultRequestChannel of the MessageGateway. This DirectChannel
utilizes the default RoundRobinLoadBalancingStrategy
which is doing a Round Robin search for the correct Outbound Adapter to send the given response through. Of course, this round robin search does not always find the appropriate Outbound Adapter on first search and when it doesn’t it logs accordingly. Not only is this producing a large amount of unwanted logging but it also raises some performance concerns as I anticipate several hundred inbound/outbound adapter combinations existing at any given time.
I am wondering if there is a way in which I can more closely correlate the inbound and outbound adapters in a way that there is no need for the round robin processing and each response can be sent directly to the corresponding outbound adapter? Ideally, I would like this to be implemented in a way that the use of a single MessageEndpoint
and single MessageGateway
can be maintained.
Note: Please limit solutions to those which use the Inbound/Outbound Adapter combinations. The use of TcpInbound/TcpOutboundGateways is not possible for my implementation as I need to send multiple responses to a single request and, to my knowledge, this can only be done with the use of inbound/outbound adapters.
To add some clarity, below is a condensed version of the current implementation described. I have tried to clear out any unrelated code just to make things easier to read...
...ANSWER
Answered 2020-Jan-03 at 15:11Well, I see now your point about round-robin
. You create many similar TCP channel adapters against the same channels. In this case it is indeed hard to distinguish one flow from another because you have a little control over those channels and their subscribers.
On of the solution would be grate with Spring Integration Java DSL and its dynamic flows: https://docs.spring.io/spring-integration/reference/html/dsl.html#java-dsl-runtime-flows
So, you would concentrate only on the flows and won't worry about runtime registration. But since you are not there and you deal just with plain Java & Annotations configuration, it is much harder for you to achieve a goal. But still...
You may be know that there is something like replyChannel
header. It is taken into an account when we don't have a outputChannel
configured. This way you would be able to have an isolated channel for each flow and the configuration would be really the same for all the flows.
So,
- I would create a new channel for each
configureAdapterCombination()
call. - Propagate this one into that method for
replyChannel.subscribe(outboundAdapter);
- Use this channel in the beginning of your particular flow to populate it into a
replyChannel
header.
This way your processQuery()
service-activator should go without an outputChannel
. It is going to be selected from the replyChannel
header for a proper outbound channel adapter correlation.
You don't need a @MessagingGateway
for such a scenario since we don't have a fixed defaultRequestChannel
any more. In the sendFirstResponse()
service method you just take a replyChannel
header and send a newly created message manually. Technically it is exactly the same what you try to do with a mentioned @MessagingGateway
.
For Java DSL variant I would go with a filter
on the PublishSubscribeChannel
to discard those messages which don't belong to the current flow. Anyway it is a different story.
Try to figure out how you can have a reply channel per flow when you configure particular configureAdapterCombination()
.

Hi I have been having trouble with an application i started using the jumpstart template from gorails.
I am finding that my I am struggling to get my js to work. For this example( there are many) I will use trix editor.
I follow the instructions
Add trix-rails to your Gemfile:
...ANSWER
Answered 2019-May-21 at 07:46As far as I know, webpacker is not going through the asset pipeline. If you have a Rails 5.x project, you can use the asset pipeline (check your Rails version in the gemfile) next to webpacker.
With the same boilerplate I made it work by following these steps:
- add to gemfile as you did and
bundle install
yarn add trix
in the command line- add
@import "trix";
toapp/assets/stylesheets/application.scss
- and then, because of the yarn install you can import it into the 'new' javascript folder
app/javascript/packs/application.js
like so:import 'trix'
With the same html code, the editor now shoes perfectly fine for me :)

QUESTION
I'm trying to upgrade from laravel 5.1 to 5.3. When attempting to run composer update, it's failing saying that I'm trying to install multiple versions of symfony/console. Part of the error is below
...ANSWER
Answered 2019-May-07 at 21:08Your error message suggests that peridot-php/peridot
package v1.16 that you require only works with symfony/console
in version ~2.0
, which is equivalent to any 2.x version and thus incompatible with 3.x version of symfony/console
which Laravel requires.
First version of peridot-php/peridot
that supports symfony/console
3.x is 1.18.1, so you need to bump your dependency to that version to support Symfony Console 3.x properly.
