kandi X-RAY | epi Summary
Creating an API can be a tedious task, and if you need to filter your data in specific ways, things are bound to get nasty. Epi comes with a controller that handles your basic CRUD tasks for an Eloquent model, but the index / "read all" method it where Epi really shines. Imagine that you have a Page model that has got a relationship with a PageTranslation model. Perhaps you would want to retrieve a page by it's slug that lives in the PageTranslation model. With Epi, it would be a simple as requesting the following URL: api/pages?filter[translation.slug]=some-slug.

QUESTION
I want to iteratively process a master list of comparisons using group_walk() or group_map() as an alternative method to import batches of .csv files.
I would like to input a dataset that looks like this:
Test Assay Var1 Var2 Freq Assay1 neg neg 19 Assay1 neg pos 5 Assay1 pos neg 8 Assay1 pos pos 141 Assay2 neg neg 25 Assay2 neg pos 6 Assay2 pos neg 17 Assay2 pos pos 33 Assay3 neg neg 99 Assay3 neg pos 20 Assay3 pos neg 5 Assay3 pos pos 105I want to use the function epi_analysis and export a csv for each Test Assay (in this example Assay1, Assay2, and Assay3). So far I have:

Answered 2021-Jun-06 at 01:50You need to call your function in group_map
. Also the function requires two arguments so pass the_dir_ex

QUESTION
I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:
...ANSWER
Answered 2021-Apr-21 at 18:50As pointed out in the comments, you can use group_by
from dplyr
to accomplish this.
First, you can extract keywords for each comment/sentence. Then unnest
so each keyword is in a separate row with a date.
Then, use group_by
with both date and comment included (to get frequency for combination of date and keyword together). The use of summarise
with n()
will give number of mentions.
Here's a complete example:
QUESTION
Every week I have to restore 2 different databases. I submit a ticket to Epi support and they give me .BAK files with different dates appended to them.
Running SQL Server 2014 (on remote server), Visual Studio 19 (on local machine), and Integration Service Project.
So far, my SSIS package removes previous .BAK files from SQL Server Backup directory, moves the new ones from my Downloads folder to the SQL Server Backup directory, and deletes one of previously existing backups (I like to delete them because WITH REPLACE does not update the LAST RESTORED DATE and I like to keep those up-to-date).
I would think that I could re-use the filename and the directory from when I move the BAK files with a File System Task in order to generate the RESTORE DATABASE statement, but I am not sure how to pass those fields in SSIS.
Now, I need to EXECUTE SQL TASK to RESTORE DATABASE, but it is hard to execute this in one statement with a dynamic filename.
I have looked at many different articles and tried different things, but none have worked.
The following script is what I want to be able to run, but I get errors even when the filename is hardcoded:
RESTORE DATABASE [Insite.Commerce.horizon.Sandbox] FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\horizon-sandbox-20210412.bak'
The errors that this draws are below:
Msg 5133, Level 16, State 1, Line 2 Directory lookup for the file "d:\sqldata\\Insite.Commerce.horizon.mdf" failed with the operating system error 21(The device is not ready.).
Msg 3156, Level 16, State 3, Line 2 File 'Insite.Commerce.horizon' cannot be restored to 'd:\sqldata\\Insite.Commerce.horizon.mdf'. Use WITH MOVE to identify a valid location for the file.
Msg 5133, Level 16, State 1, Line 2 Directory lookup for the file "l:\sqllogs\\Insite.Commerce.horizon_log.ldf" failed with the operating system error 3(The system cannot find the path specified.).
Msg 3156, Level 16, State 3, Line 2 File 'Insite.Commerce.horizon_log' cannot be restored to 'l:\sqllogs\\Insite.Commerce.horizon_log.ldf'. Use WITH MOVE to identify a valid location for the file.
Msg 3119, Level 16, State 1, Line 2 Problems were identified while planning for the RESTORE statement. Previous messages provide details.
Msg 3013, Level 16, State 1, Line 2 RESTORE DATABASE is terminating abnormally.
I am not sure how to address these errors and/or if they are even relevant because I do not know if I am going about a database restore in SSIS the right way.
Regardless, as of now, I am trying to execute the following SQL statement in SSIS in order to return the SQL statement it generates as a result or variable that can be passed to another SQL statement and then executed. See below:
...ANSWER
Answered 2021-Apr-16 at 16:29WITH MOVE needed to be used, but the DB name changed so all the logical filenames also had to change.
In short, what I did was use the UX in SSMS to set-up the database restore.
I picked my file from my device and changed the Restore To name as necessary. Then, I clicked "Script" in the top left of the Restore Database window and then clicked "New Query Editor Window".
This scripted everything out to a new query. It included the WITH MOVEs that needed to take place and a few other settings.
Although, how I got this to work in SSIS was I copied that new script to an Execute SQL Task in SSIS, but I added that text into another dynamic query that grabbed the filename I needed.
Here is the full query for the restore:

I was trying to create below AWS resources, primarily what I am trying to do is, create an ec2 instance, EIP, and attach an EIP to the AWS instance and then using provisioners I would like to execute few commands over the instance using ssh connectivity

Answered 2021-Mar-07 at 07:40There are two apparent issues in your code:
- Wrong username. It should be
ec2-user
, notec2_user
. - Wrong place for your provisioner. In your case you should use
user_data
, but for the sake of it, if you really want to use provisioner, then it must be external (remove from the instance) to the instance and usenull_resource

...ANSWER
Answered 2021-Jan-14 at 07:47Very brief overview for GCC:
GCC's .md
machine definition files tell it what instructions are available and what they do, using similar constraint syntax to GNU C inline asm. (GCC doesn't know about machine code, only asm text, that's why it can only output a .s
for as
to assemble separately.) There are also some C functions that know about generic rules for that architecture, and I guess stuff like register names.
The GCC-internals manual has a section 6.3.9 Anatomy of a Target Back End that documents where the relevant files are in the GCC source tree.

Similar to here, I try to create a loop that generates a figure with subplots from predefined functions. Those functions create different kind of figures (like line-plots or tables) and already use plt.subplots
. In the end, I want to create a figure with multiple subplots for every country in my dataset through a loop. The country specific figures shall then be saved on individual pages of a pdf file.
ANSWER
Answered 2021-Jan-08 at 02:33There are numerous mistakes in codes. PdfPages saves one figure per page. So you should generate one figure per country, with two axes (line plot and table). Full codes are as following:
