ORM uses QuerySeter to organize queries. Every method that returns QuerySeter will give you a new QuerySeter object.


Basic Usage:

expr describes fields and SQL operators in QuerySeter .

Field combination orders are decided by the relationship of tables. For example, User has a foreign key to Profile , so if you want to use Profile.Age as the condition, you have to use the expression Profile__Age . Note that the separator is double under scores __ . Expr can also append operators at the end to execute related SQL. For example, Profile__Age__gt represents condition query Profile.Age > 18 .

Comments below describe SQL statements that are similar to the expr, but may not be the exact generated results.


The supported operators:

The operators that start with i ignore case.


Default values of Filter, Exclude and Condition expr




gt / gte

lt / lte






Advanced Query API

QuerySeter is the API of advanced queries. Here are its methods:

Every API call that returns QuerySeter will give you a new QuerySeter object. It won’t affect the previous object.

Advanced queries use Filter and Exclude to do conditional queries. There are two filter rules - contain and exclude


Used to filter the result for the include conditions .

include conditions

Use AND to connect multiple filters:


Used to filter the result for the exclude conditions .

exclude conditions

Use NOT to exclude condition Use AND to connect multiple filters:

Others outside the teaching profession were not so willing to accept the governor’s financial forecasts.

Former state lawmaker David Lujan, now director of the Arizona Center for Economic Progress, recalled that lawmakers enacted a program in 1998 called Students FIRST, short for “fair and immediate resources for schools today.”

The idea was that the state would assume the burden, until then borne by local districts. More to the point, lawmakers were told all that could be done within existing revenue projections, with no new source of funds.

That proved to be an unfounded assumption. In fact, lawmakers stopped funding the construction and repair formula during the recession. The result was a lawsuit filed against the state by school districts and education groups, a legal action still pending in Maricopa County Superior Court.

#FireTheTeachers. Get rid of all the liberal teachers.

April 26, 2018 at 12:06 am

Do first responders i.e.: fire dept, police depart nurses, doctors and especially the military walk out? No. That would be a disaster. Their pay is not near what it should be for the responsibilities on their shoulders. So why do teachers think they can walk out on the most precious thing to families, their children. Yes teachers should receive more pay, but why do they feel they are entitled to demands. This is what our society has become. What other profession has the luxury of working 9 months out of the year as well numerous breaks during the school year and get paid a full years salary as well as a substantial pension when they retire. Do they realize how walking out is hurting many students as well as parents. Especially students with disabilities and the parents of these students. What about those students graduating . Saying “you must come to school on May 25 and make up the time so you can receive your diploma”. Teachers say the walk out is for students as well, but what it is doing is hurting the students and their families This walk out is about politics, money and greed. P,ease come together and compromise for everyone’s sake. Remember why you became a teacher.

I agree with you Vicky and also agree with you Jason! Fire the teachers, revoke their teaching certificates and provide parents with vouchers for private schools. Teachers in private schools make $36.000 per years , teachers in public schools make $48K to 57K per year! # FireTheTeachers!

well it will be interesting if this continues into Wednesday May 2, 2018, since the AZ state Truancy law is 5 days of missing school, (unexcused). What will state and local prosecutors consider this as being?? There is an outrageous amount of budget money in the AZDOC and especially in the private prison system. Ducey should allocate part of those funds from there into the state education as well along with the Marijuana industry. #GETOURKIDSBACKTOSCHOOL!


This systematic review used the recommendations outlined in the Cochrane Handbook for conducting systematic reviews and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to assess the quality of the evidence by outcome.

PubMed, Embase, Cochrane Library and Google Scholar electronic databases were searched from 1992, as well as grey literature.

Most studies identified were observational and of varying methodological design.

Some studies did not provide evidence for the significance of their findings.


The relationship between physicians and the pharmaceutical industry has evoked heated debate for many decades. 1 In 2012, the pharmaceutical industry spent $89.5 billion on physician–pharmaceutical sales representative (PSR) interactions that accounted for 60% of the global sales and marketing spending. Sale Gazelle LaceUp Suede Trainers Adidas adidas Big Discount Online Buy Cheap Outlet IFbneAAXl
Previous reports have demonstrated that PSRs may influence prescribing behaviour. 9–16 However, the evidence determining whether pharmaceutical industry and PSRs interactions influence physicians is divided and contradictory. Studies have indicated that physicians may be unable to distinguish between promotional information and scientific evidence. 17 18 Physicians, however, believe their colleagues are more susceptible to pharmaceutical industry marketing strategies than themselves. 19–22 The majority of the physicians do not believe that they are affected by pharmaceutical industry and PSR interactions. Most medical and governmental institutions have installed guidelines and self-regulatory and legislative checks to regulate the relationship between physicians and the pharmaceutical industry and its representatives. 5 15 16 23–26 However, while administrative proposals for deregulatory reforms that would remove some governmental authority over the industry are increasing, scientific evidence rigorously examining the extent of interactions between physicians and pharmaceutical industry and it PSRs is needed. This review evaluates critically and systemically the evidence on the impact of pharmaceutical industry and PSR interactions on physicians.

We followed a detailed methodology that we described in our review protocol, which is available on request to the corresponding author. Two independent reviewers assessed selected articles as per inclusion/exclusion criteria, shortlisted them for writing the review and cross-checked their decisions about inclusion/exclusion with each other. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines ( supplementary appendix 1 ).


Eligibility criteria

The eligibility criteria were:

We did not exclude studies based on risk of bias. We took risk of bias into account when grading the quality of evidence using GRADE approach.

types of studies: observational study design, such as cross-sectional studies and cohort studies, but also (non-)randomised trials and survey designs comparing at least one facet that are mentioned below on the impact on behaviour and attitude;

Motivated by research problems arising in the analysis of gut microbiome and metagenomic data, we consider variable selection and estimation in high-dimensional regression with compositional covariates. We propose an ℓ 1 regularization method for the linear log-contrast model that respects the unique features of compositional data. We formulate the proposed procedure as a constrained convex optimization problem and introduce a coordinate descent method of multipliers for efficient computation. In the high-dimensional setting where the dimensionality grows at most exponentially with the sample size, model selection consistency and
