QUESTION
Hey there stackoverflow
I am currently building a course application as part of my laravel project.
My problem lies in how the eloquent handle model relations, i'm still kinda new to eloquent, so hopefully you can answer my question.
The structure
The Course has many episodes and each episode has many sections.
Which means I have 3 tables in the DB. Courses -> course_episodes -> course_episode_sections
ID table is where i connect courses with users - course_users.
Right now i can create courses and and put in all the data correctly.
The Problem
I need to retrieve all the courses and its nested children that the user has bought, which is connected in the course_users table with columns course_id and user_id
Course structure
Same stucture in DB
...ANSWER
Answered 2021-Jun-14 at 15:14According to your explanation, course_users table holds many-to-many relationship between Course and User model. In case of a many-to-many relationship, you actually don't need a CourseUser model. This kind of table which holds many-to-many relationship is called pivot table. Read more from the Official Documentation
I am defining only the relationships with your Course, User, CourseEpisode, CourseEpisodeSection models.

QUESTION
I'm trying to make QTableView
auto-adjust the height whenever column width is changed, I have sub-classed QHeaderView
though I was not able to actually utilize it, I'm using sectionResized
signal of QHeaderView
whenever column width is changed, and on the basis of new columns and the string length for the column header, I'm trying to estimate the height.
ANSWER
Answered 2021-Jun-12 at 18:31Finally, with some internet searches, and with the idea of using fontMetrics and determining bounding rectangle from @SGiast on Qt Forum at How to make QTableView to adjust the height of it's horizontal header automatically in PyQt?, and with the help of SO thread: How to use QFontMetrics boundingRect to measure size?, I was able to implement the required behavior.
QUESTION
I am having a hard time understanding why the Oracle CBO is behaving the way it does when a bind variable is part of a OR condition.
My environment
Oracle 12.2 over Red Hat Linux 7
HINT. I am just providing a simplification of the query where the problem is located
...ANSWER
Answered 2021-Jun-10 at 17:36From the execution plan the optimiser is, for some reason, re-evaluating the hierarchical query for every row in your table, and then using exists()
to see if that row's ID is in the result. It isn't clear why the or
is causing that. It might be something to raise with Oracle.
From experimenting I can see three ways to at least partially work around the problem - though I'm sure there are others. The first is to move the CSV expansion to a CTE and then force that to materialize with a hint:
QUESTION
I am using lmfit for solving a non-linear optimization problem. It works fine to the point where I am trying to implement a measurement error as the standard deviation of the dependent variable y (sigma_y). My problem is, that I cannot interpret the Information criteria properly. When implementing the return (model - y)/(sigma_y)
they just raise from really low to very high values.
i.e. [left: return (model - y)
-weighting-> right: return (model - y)/(sigma_y)
]:
- chi-square 0.00159805 -> 47.3184972
- reduced chi-square 1.7756e-04 -> 5.25761080 expectation value is 1 || SO discussion
- Akaike info crit -93.2055413 -> 20.0490661 the more negative, the better
- Bayesian info crit -92.4097507 -> 20.8448566 the more negative, the better
My guess is, that this is somehow connected to bad usage of lmfit (wrong calculation of Information criteria, bad error scaling) or to a general lack of understanding these criteria (to me reduced chi-square of 5.258 (under-estimated) or 1.776e-4 (over-estimated) sounds like a really poor fit, but the plot of residuals etc. looks okay for me...)
Here is my example code that reproduces the problem:
...ANSWER
Answered 2021-Jun-12 at 02:48Well, in order for the magnitude of chi-square to be meaningful (for example, that it be around (N_data - N_varys), the scale of the uncertainties has to be correct -- giving the 1-sigma standard deviation for each observation.
It's not really possible for lmfit to detect whether the sigma you use has the right scale.

QUESTION
I have the follow situation:
- One layout with TabLayout, ViewPager and advertising banner on bottom
ANSWER
Answered 2021-Jun-11 at 05:24Is it better for me to display ads by screen or by tabs?
eCPM doesn't change much with ad placement ( on same screen ), it will definitely have impact. Recommend to play around with admob placement on various screens and measure the performance of each advert by monitoring the analytics.
There are various other factors for eCPM calculation like Country where advertisement is displayed ( e.g. an advert displayed in USA vs ad displayed in India will have different eCPM value). You app category ( game vs education app or kids category app ).
Rather than thinking about eCPM. Always think from user perspective, loading lot of advertisement gives a bad user experience and app retention might be impacted with it. Also prevent placing ad where users might click it accidentally.
Refer to this guideline for Discouraged banner implementation. https://support.google.com/admob/answer/6275345?hl=en&ref_topic=2936214
There are log of good resources provided by google to understand ad placement and how to boost your revenue with minimal disruption to end user. https://admob.google.com/home/resources/
Also rewarded ad is another good option to explore for increasing the ad revenue.
